分析了3种雷达测距体制的优缺点。针对超音速密集弹丸数量多、速度快等特点导致的脱靶量测量困难等问题，提出一种基于调频连续波体制的弹载雷达测距方法，采用四面天线收发分置结构，突破了正侧视开窗检测技术，保证目标在穿越窗口时RCS最强，并针对少数测量数据无法归类现象，设计了基于广义Hough变换的分类方法。仿真结果表明：该脱靶量测量方法可以有效区分多个弹丸轨迹。最后进行了试验验证，结果与理论分析一致，证明了该方法合理性和实用性。

Advantages and disadvantages of three radar ranging systems have been analyzed. To measure the miss distance of transonic saturated bullets,a new method based on the system of frequency modulated continuous wave is provided,adopting four antennas to receive signals. Broke through a key radar detection technology to ensure the RCS is biggest when the target is through the window. The Hough based algorithm to solve the problem of measurement data unable to be classified is designed. The simulation results show that the miss distance measurement method can effectively distinguish among multiple projectile trajectories. The test results are consistent with theoretical analysis,and proving this method is rationality and practicability.
