中文摘要：

针对未来无人机对目标高精度定位的迫切需求，开展了无人机动态目标高精度定位方法研究，提出了动态目标高精度定位总体方案。方案将惯性／卫星组合导航系统和机载光电平台系统获取的载机信息和目标相对信息作为目标定位算法的输入量，合理分配目标定位过程中各项误差参数，实现无人机对目标的高精度定位。经仿真验证，目标定位精度和栽机导航精度都达到了期望指标，表明了方案和算法的有效性。

英文摘要：

According to the urgent need of high- precision target localization to UAV, high- precision tar- get location method of UAV is researched. This paper proposes high- precision target location overall pro- gram. It collects aircraft information and target information, which are provided by the INS/GPS integrated navigation system and airborne photo- electronic system as the inputs for high- precision target location al- gorithm, and distributes targeting errors reasonably. Finally, high- precision targeting results are obtained. Simulation results show that the target location accuracy and navigation accuracy have reached the expec- ted indexes;the program and algorithm are valid.
