The numerical model of the target,typical clutter signal and deceptive jamming signal and the simulation method of radio frequency for wide-band radar were presented based on the computation of radar cross section（RCS） of the complex target in this paper.The method of the target simulation and the generation of the echo signal based on digital radio frequency memory（DRFM） technology were given out.The RCS of the complex target such as F-16 fighter was computed.The simulation results of high resolution one dimensional range image and echo signal of the target were given out.
