摘要
利用小型特种飞行器跟踪地面活动目标时,一般需采用双自由度光电跟踪器,文中提出了一种使用单轴光电跟踪器,再加上飞行器航向或速度调整实现目标跟踪的设想。进行了仿真计算和可行性研究,给出了跟踪模型和跟踪曲线,分析了影响跟踪性能的各个因素,确定了最佳初始跟踪点和最小初始跟踪距离,提出了平行跟踪算法。以上仿真分析结果对研制小型化、低成本动目标跟踪设备将会有较大的帮助。
In order to solve the problem of tracking a mobile ground target, the electro-optical sensor with two degree of freedom control is necessary according to the traditional approach. In this study, a new approach using an dectro-optical sensor with elevation control mounted on a micro air vehicle （MAV） was suggested. The heading control or velocity control of the MAV provided another degree of freedom for tracking. According to the simulation and feasibility study, the tracking model and the tracking path were given, the factors which affect the performance of tracking were analyzed, the best initial tracking position and the minimum initial distance were discovered, and also the parallel tracking method was presented. The simulation and analysis results are important reference for developing low cost miniature equipment for tracking a low speed ground target.
