Suppression of sidelobe scatterers in an AESA FMCW radar

This paper describes an active electronically scanned array (AESA) FMCW radar with eight transceivers. Each transceiver has its own direct digital synthesizer (DDS) for signal generation which enables digital beam forming on transmit as well as on receive. The coherent operation of the eight transceivers and the capability to perform digital beam forming on transmit and receive is demonstrated. Also the first results from radar measurements with suppression of sidelobe scatterers are shown.
