航空侦察是为获取敌情、地形和有关作战情报而采取的重要手段，各种电磁信号侦察、光电信号侦察在同一飞机平台的应用越来越广泛，电磁信号侦察以及地面其他系统发现目标后，通过目标的位置信息引导光电侦察系统对目标进行搜索、跟踪、查证的应用也越来越多。当机载光电平台接收到目标的坐标值后，自行接收GPS和惯导信息，并实时解算出被测目标在光电平台坐标系下的方位角和俯仰角，引导目标进入光学载荷视场内，并用图像视频跟踪的方法捕获和跟踪目标。针对飞机平台对地面固定目标或者运动目标的引导进行研究，将目标点坐标从大地坐标系转换到光电平台载机坐标系，并建立自主引导测量方程，利用蒙特卡罗统计的方法分析自主引导测量方程中各个误差因素对最终引导精度的影响，针对如何提高引导精度提出了一些建议。并在某光电平台上进行飞行试验验证，目标均能很好地进入跟踪视场内，完成捕获、跟踪功能。

Aerial reconnaissance is an important means to obtain information, terrain and other relevant intelligence of the enemy. Various of electromagnetic and photoelectric signals used in the same aircraft platform are more widely. When the target is found by other reconnaissance means, it needs the position information of the target of the photoelectric reconnaissance system to search, track and verificate. When the photoelectric platform receives the coordinates of the target value, and the GPS and inertial navigation information of the airplane, the azimuth and elevation of the measured target are calculated real﹣timely. The platform guides target into the optical payload field, and tracks the target using the image tracking video. This paper studied the methods to guide the opto﹣electronic platform to trace the fixed targets or moving targets on the ground, which established the automatic guiding measurement equation, to translate the target coordinates from geodetic coordinate to the opto﹣electronic platform coordinate system. To analyze the each factors in automatic guiding measurement equation, using Monte Carlo statistical method,and find how each factors error in measurement equation to affect the precision of the final guidance, in order to improve the guiding precision puts forward some suggestions, the target can be well guided into the track field in a flight test.
