The EL/M-2075 is a solid-state L-band conformal array radar system for use on a
Boeing 707 and other aircraft. This radar consists of an array of transmit/receive (T/R) modules that allow a beam to be electronically steered, making a physically rotating rotodome unnecessary. AESA radars operate on a pseudorandom set of frequencies and also have very short scanning rates, which makes them difficult to
detect and
jam. Up to 100 targets can be tracked simultaneously to a range of 200 nmi (370 km), while at the same time, over a dozen air-to-air interception or air-to-ground attack can be guided. The radar can be mounted on an aircraft's
fuselage or on the top inside a small dome. Either position gives the radar 360-degree coverage. The phased array radar allows positions of aircraft on operator screens to be updated every 2–4 seconds, rather than every 20–40 seconds as is the case on the rotodome AWACS. As used in its Chilean Boeing 707-based application, the lateral fairings measured approximately 12 × 2 m and were mounted on floating beds to prevent airframe flexing degrading the radar accuracy. Each array scans a given azimuth sector, providing a total coverage of 360°. Scanning is carried out electronically in both azimuth and elevation. Radar modes include high
PRF search and full track, track-while-scan, a slow scan detection mode for hovering and low-speed helicopters (using rotor blade returns) and a low PRF ship detection mode.
Platforms The system can be fitted to a number of aircraft, including the
Boeing 707,
Boeing 767 and
Boeing 747 series aircraft. Under a contract signed with Chile in 1989, the first Phalcon system to be installed was fitted to a former
LanChile Boeing 707, and was first flown in 1993. In May 1994, the aircraft was delivered to the
Chilean Air Force, where it is known as the Condor. ==Operators==
