Abstract: The frequency modulated continuous wave circular synthetic aperture radar (FMCW CSAR) is a high resolution imaging radar, which has always played an important role in target recognition.

Abstract: To combat the Doppler shift caused by high mobility, orthogonal time frequency space (OTFS) systems have been proposed to convert the timevarying channel into a nearly time-invariant channel ...
