A novel radar’s ranging method named as motion accumulation ranging algorithm is proposed, this ranging method is based on the motion of the target relative to the radar itself,and the range value is deter-mined by the range characteristics at different time.The motion accumulation ranging algorithm operates under high pulse repetition frequency(PRF)pulsed-Doppler mode,and the location of the target is determined by the evaluation of the signal power modulation of radar echoes.The motion accumulation location algorithm theory, the calculation method and the simulation results of this movement accumulation ranging algorithm are given. The experimental results show that high PRF waveform radar motion accumulation location algorithm can accu-rately estimate the distance between target to radar.
