基于光电观测信息的空中机动平台被动跟踪研究

Research on aerial maneuvering platform passive tracking based on photoelectron

针对强电磁环境下机载雷达测量精度较低的问题,研究提出了一种基于机载光电观测信息的被动跟踪方法,讨论了其目标运动分析问题。利用光电探测设备测量的目标方位角、高低角,结合平台的导航信息,建立了基于最小二乘准则的目标函数,对目标实施了精确定位,并对观测数据中野值的剔除问题进行了分析。通过蒙特.卡洛模拟仿真,试验结果表明:该方法能够较为准确、快速地收敛至真值附近。

The bearings-only tracking based on recursive least square theory is applied to the passive tracking of an aerial maneuvering platform. The motion of targets is analyzed. With the photoelectrical measurement of azimuth angles, elevation angles and navigation information induced from the platform, the precise localiza tion of targets is accomplished. The problem of the outlier removal is also discussed. The Monte Carlo simulation experiment results demonstrate that the caleulative amount is small.
