中文摘要：

针对单个模型跟踪机动目标的性能不够理想、多模型方法最优模型集设计困难且算法较复杂的问题．基于“当前”模型，从目标与跟踪雷达的相对角运动出发，提出一种能适应多类飞行器的自适应跟踪单模型，并给出了优化估计目标与雷达的相对角运动及距离运动的算法．仿真结果表明．该自适应单模型跟踪性能稳定，远优于“当前”模型，对于强机动飞行的目标，其跟踪性能要优于交互多模型方法（IMM），而且其计算量要低于IMM．

英文摘要：

To the problem of dissatisfied single model tracking and the design of the optimal model-set of multiple- model （MM） algorithm being difficult, a kind of single adaptive model and algorithm are proposed to track the relative angular motion of aircrafts and radar based on the modified ＂Current＂ model. Simulation results show that tracking performance of this proposed adaptive model is improved much more than the ＂Current＂ model, and better than the interacting multiple-model （IMM） for the strong maneuvering target tracking. Furthermore, the computational load of the proposed model is less than that of IMM.
