Abstract

Coherent pulse train can obtain high Doppler resolution, but leads to range and Doppler ambiguity. Thus, the staggered pulse repetition frequencies (PRFs) is proposed to extend the unambiguous range or Doppler coverage. However, there are various disadvantages in pulse-to-pulse stagger or block-to-block stagger. In this paper, inspired by the Doppler compensation processing, we propose a modified range-Doppler (RD) processing method. Moreover, a waveform design scheme matching this method is also presented. The modified RD processing associated with the designed waveform can effectively extend the unambiguous Doppler coverage without affecting the unambiguous range. Experimental evidence verified the effectiveness of the modified RD processing method and the designed waveform.
