摘　　要：自稳定跟踪技术是机动平台光电经纬仪跟踪的关键技术。针对提高基于机动平台光电经纬仪的自稳定跟踪、定位精度,研究了基于机动平台光电经纬仪的自稳定跟踪技术。通过坐标变换技术将目标点从平台坐标系转换到大地坐标系中,给出了一种基于坐标变换的机动平台预推跟踪方法,通过坐标转换将当前几帧合成角数据转换到大地坐标系,并由合成角轨迹预推下一帧合成角数据,然后将预推结果转换到平台坐标系,实现了机动平台的稳定跟踪。对比了该预推结果和在平台坐标系直接预推结果,表明该预推方法更为准确,更适于实现机动平台的稳定跟踪。The self-stabilization tracking technique is the key technique for theodolite tracking based on the mobile platform.To improve the tracking and positioning accuracy,the self-stabilization tracking technique based on mobile platform was studied.In the technique,the position of object was transformed from the platform coordinate system to the earth coordinate system by using coordinate transform.A method of forecast tracking technique based on mobile platform was presented.The former complex angle was transformed from the platform coordinate to the earth coordinate and the next complex angle was forecasted according to the trajectory of the complex angle.In the end,the forecast result was transformed back to the platform coordinate.By this means,the stable tracking technique based on mobile platform was realized.In comparison with the direct forecast result in platform coordinate,the forecast technique presented in the paper is more accurate and appropriate to realize stable tracking on mobile platform.
