-18A
The AN/TPN-18A is a lightweight, helicopter-transportable radar set designed for use during all weather conditions. The radar set is used at forward airstrips and heliports and provides information used for air traffic control, ASR, and GCA landing of aircraft. The radar set consists of three major groups of equipment: a radar set group and two control-indicator groups. The radar set group contains the receiver-transmitter group (complete radar receiver and radar transmitter systems, including DC power supplies) mounted on the antenna pedestal (base pedestal). The elevation antenna, azimuth antenna, both antenna drives, and yoke and servo actuators, all part of the radar set group, are mounted on top of the receiver-transmitter group. The two control-indicator groups are identical. Each control-indicator group consists of a control-indicator with its tubular frame and is a single-package unit containing indicator (radar display CRT) with its associated power supply and controls for remote operation (up to 76 meters) of the radar set.

TPQ-2 - Mortar counter battery;
Frequency: 600 MHz;
Notes: Derived from TPS-3

TPQ-3 - Mortar location
Description: The AN/TPQ-3 consisted of a modified AN/TPS-3 plus certain additions to provide more accurate range and azimuth data.  When the AN/TPS-3 was converted to the AN/TPQ-3, several minor modifications were made; the 20-mile range on the PPI scope was converted to a 10,000-yard range and the sweeping mechanism converted to produce OFF-center PPI operation. No changes were made to the A-scope since it was not used in mortar locating. The sweep selsyn in the antenna pedestal was replaced with a small data transmission selsyn.  In addition to these simple changes, a completely new piece of equipment called a control unit was developed.  This unit contained an accurate range unit and an accurate azimuth indicating device with a built-in sector scan switch.  Each of these units was mounted on a separate chassis which could be easily removed for servicing.

Notes: 1940-1945, 45 procured. The AN/TPQ-3, one of the first sets to be used for locating mortars, was the only mortar locator classified as standard by Army Ground Forces. It consisted of an AN/TPS-3, modified to improve its accuracy. As this set had no means for positioning its antenna in elevation, its locating technique depended entirely on azimuth and range data. In operation as a mortar locator, the set was usually sited behind a low hill in such a way as to screen out as much ground clutter as possible and yet allow the mortar shell to be picked up fairly close to the ground. A sector was scanned until a mortar shell echo was noted by the operator. The azimuth and range where the mortar echo first appeared and the azimuth and range of the point where it was last visible were recorded and plotted to scale. The line joining these points represented the ground protection of the trajectory. To find the position of the mortar it was necessary to extend this line backward from the first plotted point.

TPQ-4 - Mortar counter battery
Range: Maximum, 3,000 - 4,000 yards
Notes: The AN/TPQ-4 was, basically, an AN/APS-3 modified for ground operation with auxiliary precision ranging and azimuth marking circuits added.  The development model was designed and constructed by Bell Telephone Laboratories in conjunction with Signal Corps Engineering Laboratories in six months; an outstanding performance even in wartime. Azimuth scanning was accomplished by means of a Lewis scanner. The Lewis type of scanner was considered to be mechanically superior to the Foster scanner and therefore more desirable for field use. Vertical directivity was accomplished by the use of another Bell Telephone Laboratory development, the metal lens. The pencil beam produced by the complete antenna system was approximately 0.6º in the vertical plane and 1.0º in the horizontal plane; extreme directivity in the vertical plane was desirable in order to permit the positioning of the beam at a low angle, (the accuracy of the two point system was predicted on the ability of the radar equipment to detect the mortar shell-at low elevations). Azimuth, elevation, and range data were supplied by inter-connection and servo mechanisms so that when the operator set the azimuth and range cursors on the mortar shell echoes, as seen on the oscilloscope, mortar location was automatically computed. Provisions were also available by means of which the mortar location could be recomputed if map references indicated that the mortar was higher or lower than the radar set. As a protection to the personnel, suitable cabling was provided to permit operation at a distance of 300' from the antenna system.

Notes: The FIREFINDER operates from a shelter that can be transported by a HMMWV.  It is a computer-controlled, electronically scanned radar that uses a “fence” of pencil-shaped beams (adjustable according to the terrain) that sweep several times a second along a 90-degree sector of the horizon.
When an object penetrates the fence, the radar immediately transmits an automatic verification beam.  Should the beam also detect the target, the computer commands a rapid succession of tracking beams at a much higher data rate.  The radar continues to scan and locate other targets and develop tracks on them while it tracks the original target.  Each projectile has a separate track channel, with one additional channel designated to perform uninterrupted scanning for new targets.

When the computer determines that a target is valid, it evaluates the measured track data and calculates a trajectory that extrapolates back to the firing location.  This is displayed on a visual map and printed out in map coordinates, which can be fed to a computer-based, tactical fire-control system.
The TPQ-47(V) is designed to handle dense barrage fire automatically.  The heart of the system is a high-speed computer that controls beam placement, stores data from each radar return, and then carries out the trajectory-fitting calculation that pinpoints the hostile weapon location.  The radar’s built-in “censoring” feature adapts it to high-density environments and ensures that the radar is tracking projectiles from newly located weapons rather than repeating data on the same one.

Fault-detection constantly monitors the performance of each subsystem, providing system status information to the operator.  Built-in test equipment isolates problems and indicates their location. 
The TPQ-47(V) is designed to detect tactical ballistic missiles at ranges out to 300 kilometers and interface with tactical ballistic missile systems.

It is to be fully integrated into the targeting structure by interfacing with the Advanced Field Artillery Tactical Data System (AFATDS) and designed so it can be driven on and off a C-130 transport aircraft, providing high mobility, ease of transport, and high survivability.  The new design features improved automation, allowing for a reduction in crew size.  It can be operated by six people.

The design doubled FIREFINDER detection range for mortar, artillery, and rocket fire.  It would have had an added ability to interface with a Theater Missile Defense System, and rapid counterfire would be made possible by incorporating AFATDS software.  The upgrade design planned to reduce the false alarm rate from one per hour to less than one in 12 hours.  Because of FIREFINDER’s modular, field-repairable design, downtime is minimized and most maintenance tasks would be performed at unit level.  An auto-calibration algorithm allows for re-calibration of the antenna in the field after repair.

Notes:

Bell Telephone Laboratories developed this radar that subsequently was produced by the Western Electric Company. A crew of two could operate the radar. The 1B model could detect bombers at 10,000 feet at a distance of 120 nautical miles. The height detection and range on the 1C and 1D models exceeded those of the 1B. The transmitter sent its pulse at an L-band frequency between 1220 to 1280 megahertz (MHz). (Ref: Searching the Skies)

The present defense acquisition radars (DAR) have evolved from the early warning radar AN/TPS-1. This radar included only the essentials required to provide early warning information. Similar but not identical equipment, the SCR-602A, appeared in the military radar inventory during World War II. Later the AN/TPS-1B radar was designed. The addition of moving target indicator circuits to the AN/TPS-1 produced the AN/TPS-1D, a medium-power search radar designed to detect targets in excess of 290 kilometers. It was first employed by the Air Force and the Navy.

Subsequent issue of the AN/TPS-1D satisfied the requirement for long-range radars at battalion level in air defense artillery units. In 1957, further improvements were provided by more stable moving target indicator circuits, better vertical antenna coverage, and a better display system which changed the nomenclature to AN/TPS-1G.

To make the AN/TPS-1D and AN/TPS 1G radars more compatible with unit mobility, they were packaged in a metal shelter, They also were assigned a new name, electronic search central AN/GSS-1. In addition to the radar, the shelter contains radio and telephone facilities, IFF equipment, and a manual plotting board. The shelter can be mounted on a 2.5-ton truck and can serve as an emergency battalion AADCP. (Ref: US Army Air Defense Digest, 1972)

 MIT’s Radiation Laboratory developed and produced the first version of this radar near the end of World War II. Zenith produced the A-model sets in the post-war period.
The vertically mounted antenna was three feet wide and ten feet long. Two operators were needed to run the set. The initial model operated at a frequency of 9000 to 9160 MHz and had a maximum reliable range for bombers of 60 miles at 10,000 feet.
An updated version designated the AN/FPS-4 was produced by the Radio Corporation Of America (RCA) beginning in 1948. Some 450 copies of this and the trailer-mounted AN/MPS-8 versions were built between 1948 and 1955. (Ref: Searching the Skies)

This must be accomplished in a search mode in the presence of weather clutter and friendly and unfriendly interference. The AN/TPS-35 also j supplies interrogation pulses to the aircraft to enable the proper identification of the aircraft by the system, The AN/TPS-35 supplies. the aircraft position information to the main control room (RAPCON), which
may be as much as 15 miles away. The remote control and data signals are transmitted and received over the path by the use of an electronic microwave remoting system. All the necessary signals required for operation are carried by the microwave system to increase the flexibility I [bility of the AN/TPS-35 Search Radar System.
The Radar System, AN/TPS-35, is capable of operating without the use of the AN/TSQ-47 System if it is ever required. By use of the UHF communications and the self-contained SIF/IFF equipment, the Search Radar System may be sent out as a self-contained unit.

TPS-40 - Height Finder
The AN/TPS-40 is a highly mobile, high powered, long range radar set which provides height information on aircraft. Azimuth orientation is provided by either time-sharing control of the AN/TPS-40 among a maximum of four search plan position indicator (PPI) operators, or by control of the range-height indicator (RHI) operator. Height information from the RHI may be supplied to the PPI operators by voice from the RHI operator. However, with some PPI's, height information may be transmitted to the indicator height readout dials. Although normally transmitted in four M-35 trucks, the light weight aluminum construction of the AN/TPS-40 permits airlift by either rotary or fixed wing aircraft. In addition, the AN/TPS-40 is compatible with the AN/MPS-11, and most other search radar sets.

Notes: Marine Corps Radar; Early Warning; Situational Awareness Radar; An estimated 21 TPS-59(V) radars were produced, nine FMS orders, And nine TPS-59M/34 radars have been produced. Cost: $12.6 million.
Notes: The TPS-59(V) system is a phased-array tactical radar designed to provide long-range surveillance for the Tactical Air Operations Center (TAOC-85 or TYQ-23(V)).  The radar has a solid-state transmitter and a rotating planar array antenna.  The displays and processors are housed in two standard S-280 military shelters that include a UYK-7(V) general-purpose digital computer and three 45 kW diesel generators.

The antenna uses 54 identical row/feed networks, 27 power supplies, and a digital signal processor to control the beam pattern and process the returned signals.  The smaller TPS-59M/34 uses 34 identical row/feed networks and 17 power supplies.  The low-level transceivers include power supplies, transmitters, preamplifiers, phase shifters, duplex ers, and logic control circuitry.  There is one column feed assembly and one monitor feed assembly in the TPS-59(V).  There are three and one, respectively, in the TPS-59M/34.  The feeds distribute power vertically on the antenna scanning the elevation plane.

During operation, the self-erecting array antenna rotates mechanically in azimuth while a pencil beam electronically scans in elevation from 0° to 19°.  This is the key to the radar’s 3D capability.  The scanning covers the specified surveillance volume in a raster-scan pattern.
Two basic surveillance waveforms are used:  one for the short-range interval (5.5 to 185 km) which requires 11 pencil beams, and another for the long-range interval (from 185 km to the limits of coverage) which requires eight pencil beams.

The system was designed to counter the effects of multi-path propagation.  For optimal system performance, a special weather mode adjusts energy management and processing every five minutes according to weather conditions.

Three trailer assemblies carry the system.  The radar can be transported by helicopter, 2.5 ton truck, C-130 aircraft, rail, or seagoing vessel.

Notes: Derivative of TPS-43E. An estimated 213 TPS-43/70/75 radars have been produced. It was designed for long-range, three-dimensional, high-reliability performance in a tactical environment.  A low sidelobe antenna and advanced processing provide high-probability target detection in a heavy clutter or jamming environment with a low false alarm rate.

It is an export version of the original TPS-43(V) tactical radar, employing a fan of multiple receive beams rather than a single “pencil beam.”  The multiple beams pro­vide elevation data while physical rotation is used for azimuth scanning.  This increases target illumination per antenna scan.

The low sidelobe antenna does not use phase shifters.  It uses 36 horizontal waveguide sticks; each stick has 94 slots to provide the 1.6° beamwidth and low sidelobes.  These components were originally developed for the AWACS APY-1/2(V) radar.  Twenty-two sticks are illuminated on transmit for an elevation beamwidth of 20°.  Illumination is tapered to provide higher gain at lower elevations.  On receive, energy from 36 sticks is combined to provide six simultaneous beams.  The elevation beamwidth varies from 2.3 degrees for the lowest beam to 6 degrees for the highest.

History:
Background:  The TPS-43(V) went into production in 1966, with initial deliveries in 1970.  By 1980, large numbers of the radar were in use with both American and foreign services. In FY88, Westinghouse produced and stored 19 ULSA's and began retrofitting the first of the US units.  The ULSA and updated electronics package were installed only on US radars. On April 22, 1994, the Air Force announced that it would award a contract to design, develop, integrate, test, install, and deliver theater missile defense kits to upgrade four TPS-75(V) radars and four TYQ-23(V) modular control equipment operations modules.  These kits would be installed in the field since the radars and operations modules (OMs) are deployed worldwide. Radar System Shelter Replacement (RSSR) Acquisition.  In August 1997, the USAF Electronic Systems Center awarded a contract to acquire new shelters for the TPS‑75(V) radar system.  Plans carried options for a production run of a minimum of two and potential total of 20 to 60 shelters.  Three to 15 shelters would be produced per year over a five-year period.
