| (documentation AESAAntenna EnglishLanguage "AESAAntenna (AESA) is a type of phased array antenna, each antenna element is connected to a small solid-state transmit/ receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/ or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/ or receiver through phase shifters under the control of the computer. AESA's main use is in radar and these are known as active phased-array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased-array technology. The AESA can radiate multiple beams of radio waves at multiple frequencies simultaneously.
