基于遥测参数的雷达寻的反舰导弹脱靶量估算方法

笔者针对光学测量、无线电测量以及GPS测量等常用脱靶量测量方法的局限性，研究了利用导弹姿态角、速度以及雷达框架角估算反舰导弹脱靶量的方法，用坐标转换的方法推导了视线角与已知遥测参数的函数关系，给出了脱靶量估算的数学模型，并利用以往靶场试验的遥测数据对脱靶量进行了估算验证。经复算验证和比对分析表明：估算方法正确，适用于雷达点源目标的脱靶量估算，估算精度与GPS测量精度相当，既是对传统脱靶量测量方法的辅助和补充，又是对通过测量得到的脱靶量数据的检验和验证，可以应用于靶场试验。

Estimation Methods of Radar-seeker Missile Miss Distance Based on Telemetry Data

Aiming at the limit of common miss distance measuring methods in common using, including optics-measuring, radio-measuring and GPS-measuring, estimation method of anti-ship missile miss distance based on the missile attitude angle, speed, and radar framework angle is studied. The estimation method and mathematical model are given through coordinate transformation by deducing the function of angle of sight and the known telemetry parameters. Miss distance is analyzed through using the previous telemetry data of range test, which shows the estimation method is correct, it is suitable for point radar garget, and that estimate accuracy is the same with GPS measuring accuracy. It not only is an auxiliary and a complement to traditional miss distance measurement method, but also is an inspection and a verification to the miss distance obtained by measuring data. The estimation method can be applied in range test.
