摘　　要：脉冲追赶式同步扫描过程中,双基地雷达的目标分辨力不仅与雷达参数有关,而且还与脉冲追赶进程密切相关。分析了双基地雷达距离、角度和多普勒分辨力的影响因素,并对其在脉冲追赶情况下的变化规律进行分析,结果表明在每一脉冲追赶扫描周期内,双基地雷达的距离分辨力和多普勒分辨力不断提高,而角度分辨力则有所下降。In the process of pulse-purse module synchronization scanning, the target resolution is not only relative to the radar performance, but also has intimate correlation to the pulse pursing procession. The varied influencing factors to the histatic radar distance, angle and Doppler resolution are analyzed in this paper, and their change law is discussed also. The conclusion shows that in every pulse pursing periodic time, both the distance resolution and the Doppler are meliorated, but the angle resolution decreases.
