In order to reduce the effect of clutter echo on detection performance of CW radar,the basic principle of MTI is introduced and an implementation method for MTI in pseudo-random code phase modulation continuous wave(PRCPM-CW) radar is proposed.The different effects of the method on high velocity target and low velocity target and the effect of different multiple interval cycles on the processing performance of MTI are compared and analyzed in detail.Through the method,the clutter is suppressed,the performance of PRCPM-CW radar in clutter region is improved,and the loss of low velocity target is decreased.Simulation results show that MTI has great application value in CW radar.
