脱靶量可以通过安装在靶标上的无线电多普勒脱靶量测量设备进行测量,也能够通过对雷达测量得到的目标和导弹的数据进行处理,利用一定方法计算直接求出脱靶量。通过以靶场雷达测量得到的导弹和靶标的位置数据为基础,重点研究脱靶量的求解算法,并对该算法进行仿真。结果表明,外推算法可有效的提高脱靶量测量的精度,并基本满足实际应用中的精度及置信度的要求。 The miss distance can be measured by a radio Doppler miss distance measuring device installed on the target, and the data of the target and the missile measured by the radar can also be processed, and the miss distance can be directly calculated by a certain method. Based on the data of missile and target position measured by range radar, the algorithm of solving miss distance is studied emphatically and the algorithm is simulated. The results show that the extrapolation algorithm can effectively improve the accuracy of miss distance measurement and meet the requirements of accuracy and confidence in practical application.
