Indian EL/M-2075 Phalcon AEW&C system
Phalcon uses the Active Electronically Scanned Array (AESA), an active phased array radar. This radar consists of an array 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 the 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.
