Abstract :
Imaging approach based on range-Doppler algorithm for monostatic SAR is extended to bistatic case. Because of that the transmitter and receiver are located separately, the range cell migration phenomena of bistatic SAR is more complicated than that of monostatic case. In this paper, a simple method of range cell migration correction is used instead of interpolation operation in traditional range-Doppler algorithm for monostatic SAR. Point scatter response, range and azimuth resolutions are also discussed. The simulation results are presented.
