Abstract :
In radar signal processing, clutter suppressing and moving targets detection are basic problems. In order to detect the weak targets effectively, a novel method of long-term coherent integrated moving-target-detection based on the fractional Fourier transform is proposed in this paper. This method can compensate the Doppler migration and suppress the clutter effectively by using the discrete FRFT as the swept-frequency filter bank. The simulation results show that it has better performance of weak targets detection than the classical MTD and its computation burden is acceptable, which prove the validity of this method
