India has agreed to buy eight Raytheon Co. long-range, weapon-locating radars in the first major U.S.-Indian weapons deal in more than 10 years.The package, worth up to $146 million if all options are exercised, consists of eight counter-battery AN/TPQ-37 Firefinder radar systems plus advanced communications and support equipment, training and logistics services, the Pentagon's Defense Security Cooperation Agency said. The radar sets are designed to pinpoint long-range mortars, artillery and rocket launchers after tracking a shell for only a few seconds.
RAYTHEON - ARTILLERY WEAPON LOCATING AND AIR DEFENSE RADAR SYSTEMS
Raytheon’s Electronics Systems division produces a range of battlefield radars including the Sentinel 3-D Tactical Air Defense Radar and the FireFinder Field Artillery Weapon Locating Radars.
FIREFINDER FIELD ARTILLERY WEAPON LOCATING RADARS
Within seconds, Firefinder radar systems detect and backplot the fire of adversary weapons—artillery, rockets and mortars, to provide pinpoint targeting information for the counterattack. The systems also correct and improve the delivery of friendly fire.
Firefinder radars scan electronically in three dimensions. The stationary antenna sweeps a rapid sequence of beams along the horizon, forming an electronic radar curtain over a 90° area. Any target penetrating the curtain triggers an immediate verification beam. Upon verification, an automatic tracking sequence begins.
While tracking any single target, the radar continues scanning, locating, and tracking others. Signal and data processors test each track to filter out birds, aircraft, and other unwanted returns, giving Firefinder radars an extremely low false-location rate and a very high probability of location rating. Once the computer establishes a target's validity, it smooths the measured track data, deriving a trajectory that it extrapolates to establish the target's firing position and impact location. Those data are displayed on a visual map and printed out in map coordinates.
Over 350 Firefinder radars are in use today by seventeen nations. Some nations have adopted both the AN/TPQ-36 and AN/TPQ-37, dividing their missions between direct and general field artillery support while other nations have adopted the medium range AN/TPQ-36 for its particular suitability for peacekeeping and contingency operations, or the AN/TPQ-37 for its ability to deal with long range threat weapons.
AN/TPQ-37 FIREFINDER
AN/TPQ-37 Firefinder is a long-range 3-D weapon-locating radar system with double the performance of the AN/TPQ-36, locating long-range weapons out to 50 km. When long-range surface to surface missiles must be located, a special 60-degree sector mode extends the AN/TPQ-37's range even further. The AN/TPQ-37 operates at S (F) band.
