The EL/W-2090 is a further development of EL/M-2075 and EL/W-2085. The EL/W-2090 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.
