为了解决舰炮对海上目标射击脱靶量实时检测难的问题, 改进舰炮对海射击观测和射击校正手段, 提高舰炮实战化水平, 在航空摄影测量学和无人机目标定位技术的基础上, 通过构建目标、炸点及像点在成像空间中的几何关系模型, 并利用最小二乘法, 推导出了基于双无人机机载光电平台的目标和炸点同时定位的模型。再结合舰船经纬度信息, 经高斯平均引数反算公式计算得到炸点与目标之间的脱靶量。最后利用蒙特卡罗法对脱靶量检测模型进行仿真, 分析其误差特性。

The purpose of this paper is to solve the problem that the naval gun can't detect the miss distance of the marine target in real time, to improve the methods of the naval gun's shooting observation and shooting correction for marine targets, and to enhance the ability of the naval gun in real combat.Firstly, based on aerial photogrammetry and the UAV's target positioning technology, the dual UAV model for simultaneous positioning of targets and burst points on the photovoltaic platform is deduced by constructing the model of the geometric relationship between the target, the burst point and the image point in the imaging space and by using the least squares method.Secondly, considering the latitude and longitude information of the naval ship, the miss distance between the burst point and the target is calculated by using the Gaussian average quotation inversion formula.Finally, the miss distance detection model is simulated by using Monte Carlo method and its error characteristics are analyzed.
