Electronically scanned array — An electronically scanned array (ESA), or a phased array, offers many advantages over mechanically scanned antennas such as instantaneous beam scanning, the availability of multiple concurrent agile beams and concurrently operating radar modes.… … Wikipedia
Active Electronically Scanned Array — An Electronically Scanned Array (AESA), also known as active phased array radar is a type of radar whose transmitter and receiver functions are composed of numerous small transmit/receive (T/R) modules. AESA radars feature short to instantaneous… … Wikipedia
Conical scanning — is a system used in early radar units to improve their accuracy, as well as making it easier to steer the antenna properly to point at a target. Conical scanning is similar in concept to the earlier lobe switching concept used on some of the… … Wikipedia
