摘　　要：针对导弹脱靶量数据处理精度要求高的需求,建立了分析同帧画幅测量导弹脱靶量精度的模型。根据试验和测量特点,定义了同帧画幅测量的概念,利用同帧画幅测量弹靶之间的相关性,推导了同帧画幅测量脱靶量计算和精度估计公式,分析了影响脱靶量精度的因素,重点研究了测距、测量站交会角和测量方位角3个因素对脱靶量精度的影响,对试验中出现的典型数值进行了计算,分别给出了脱靶量精度与3个影响因素的函数关系模型,为同帧画幅脱靶量精度评估提供理论依据。The missiles miss distance accuracy requirement is very high, In this paper, establish a model to analyze the same frame format missile miss distance measurement accuracy. According to the test and measurement features , defines the concept of the same frame measurements , using the correlation with the frame format measuring projectile and target between the derived formula with frame frame measuring off-target calculation and precision of estimates , analyzes the factors that influence the miss distance accuracy , focused on the effects of distance , measuring stations and measuring the azimuth angle of intersection of the three factors on miss distance accuracy , typical numerical experiments appear to be calculated, are given as a function of the amount of off-target accuracy with three factors of relational model provides a theoretical basis for the same frame format miss distance accuracy assessment.
