Aesa true dual beam full range, full doppler spectrum imaging while scanning radar system

Abstract

A radar system accomplishes imaging and simultaneous scanning, and includes: dual waveform generators, beam formers, and phase shifters, and a shared transmit/receive module at each antenna element. The first waveform generator generates a first frequency that's constituted into a first radar beam by the first beam former then steered by the first phase shifter followed by the transmit/receive module sending a high power signal in the direction of the target being imaged. A second waveform generator generates a second frequency that's constituted into a second beam by the second beam former, steered by the second phase shifter, and transmitted by the same T/R/module, using sequential timing to provide a scanning beam of the surveillance area. On receive, the common T/R module drives the respective phase shifters, the beam formers to form the respective beams, including the beam staring at the target being imaged, and the beam performing surveillance.
