This summary presents a bistatic SAR DPCA technique for detection moving targets with one transmitter channel and two receiver channels. Because the transmitter and the receiver are located on different platforms, the transmitter position changes with time, resulting in the traditional DPCA limitation condition can’t be met. This technique applies dechirp operation in azimuth phase for each channel in echo domain to eliminate the impact of the transmitter movement, and then the constant phase error for each pixel is compensated in image domain. Through the above processes, clutter background can be suppressed by the proposed DPCA technique. Numerical simulations show the effectiveness of the technique.
