前言在脈冲多卜勒雷达系统中,为了不出现测速模糊,需要把脈冲重复频率(PRF)选得足够高,以便用频谱分离技术把运动目标从强地物杂波背景中检测出来。但是随着PRF的提高,又带来了测距模糊。因此,克服测距模糊又成了脈冲多卜勒雷达系统必须解决的课题之一。
Introduction In pulsed Doppler radar systems, the pulse repetition frequency (PRF) needs to be chosen high enough so that moving objects are detected from strong clutter backgrounds using spectrum separation techniques in order to avoid ambiguity in velocity. However, with the improvement of the PRF, blurring of the ranging is brought. Therefore, to overcome the ambiguity of ranging has become one of the topics to be solved by the pulsed Doppler radar system.
