(FMCW) modulation for range resolution, which enables them to operate with a relatively low transmit power of a few watts only. Sometimes these types of radars are referred to as “silent radar”. This paper discusses the signal processing chain from deramping the received signal down to processing of range-Doppler-azimuth spectra. By deramping the frequency modulated continuous wave (FMCW) signals, the proposed radar system is able to digitize received signals at a relatively low sampling rate and thus the imaging processing is simplified. A prototype system of this design has been developed and the initial experimental imaging results are presented in Section 0.
