Firstly, the echo model of moving target for SAR is constructed in this paper. According to model, method detection targets based on Matched Fourier Transform discussed. Compared with bilinear time-frequency distribution algorithms, will not be affected by cross-terms when multiple exist. Moreover, because remaining Doppler frequency, spectrum strong widened, and then weak shadowed one. To solve problem, CLEAN technique domain proposed targets. The simulation results validate effectiveness method.
