机载光电吊舱目标定位技术研究

Research on Airborne Optoelectronic Pod Target Location Method

介绍了机载光电吊舱目标定位所采用的齐次坐标转换法,即应用全球定位系统技术,获取载机及已知目标的位置信息,以及载机姿态信息,建立辅助坐标系,构建定位坐标转换方程,对目标定位过程进行推导,在此基础上利用蒙特卡罗方法,在MATLAB平台上编写了光电吊舱定位过程的误差仿真程序,对目标定位结果进行了误差分析。分析过程和结果具有一定的参考价值和工程适用性。

This paper introduces airborne optoelectronic pod target localization that uses the homogeneous coordinate trans- formation method,which obtains the location and attitude information of aircraft and known target,establishes auxiliary coor- dinate system and the coordinate transformation equation by GPS technology.The target-positioning process is deduced in de- tail.On this basis,error-simulation program of coordinate conversion of optoelectronic pod was written by using Monte Carlo method in MATLAB,the effect of positioning result by simulation was analyzed.The analysis of process and result have cer- tain reference value and engineering applicability.
