A frequency domain system identification based multiple-input multiple-output (FDSI-MIMO) SAR algorithm is proposed to obtain high resolution wide swath imaging. In this paper, a frequency division multiple access (FDMA) is adopted in such a way that each transmitter emits a conventional linear frequency modulated (LFM) waveform modulated by a different carrier frequency and the obtained range resolution corresponds to the total transmitted bandwidth. The proposed method is free from inter-range cell interference (IRCI). In addition, a low PRF which is less than the Doppler bandwidth is used to obtain wide swath and the Doppler aliased spectrum is recovered using spatial filters.
