Stepped-Frequency waveform processing for moving target based on genetic-CLEAN algorithm

Stepped-Frequency waveform (SFW) is a very important type of high range resolution radar signal. A novel processing method for SFW based on genetic algorithm and CLEAN technique is proposed in this paper. The parameters (i.e., position, amplitude and velocity) of a point scatterer can be found by global searching with genetic algorithm. And an iterative CLEAN processing is used to eliminate the extracted point from the received data of one SFW burst. Then the high range resolution profile (HRRP) of the target can be reconstructed with the estimated parameters. Finally the effectiveness of the algorithm is verified by the simulation results.
