论证了脱靶量测量误差在闭环校正中的地位和作用，定量分析了雷达测距误差、测角误差、检测波门的设置和目标、弹丸运动的速度、方向等因素对脱靶量测量误差的影响，估算了现有条件下脱靶量的测量精度。 The effect of miss distance measurement error on closed-loop calibration is demonstrated. The effects of radar ranging error, angle measurement error, detection wave gate setting and target, projectile velocity and direction on the error of miss distance measurement are analyzed quantitatively , Estimated the measurement accuracy of miss distance under the existing conditions.
