靶载光电脱靶量测量系统设计

Design of Photoelectric Miss Distance Measurement System Based on Target Ship

针对靶场试验需求,在靶船上设计了脱靶量测量系统。基于双站交会测量方法,采用4台高速摄像系统,将其分别布置在靶船的艏艉,实现方位360°周视成像;不同作用距离下对成像大小进行了计算,得出在50m作用距离下,最小交汇角达10°时,交会测量误差不大于3m;计算了靶船摇摆带来的系统误差。该系统实现了对试验中目标着靶末段落点偏差测量。

According to the test requirements of target range,a photoelectric miss distance measurement system was designed on the target ship. Based on the method of double station intersection,the azimuth 360° panoramic imaging was realized by using 4 high-speed video cameras arranged on the starboard of the target ship. The image size was calculated in different action distance,it was concluded that the minimum intersection angle was 10 degrees under the action distance of 50 m and the intersection measurement error was not more than 3m. The error was calculated caused by the target ship swing. The measurement of the terminal target point deviation can be realized by the system in experiment.
