摘　　要：通过多假设的方法,把机载火控雷达高重复频率线性调频测距模式下的目标距离估计和模糊分辨问题转变为静态多模型估计和判决问题。同时给出了基于这种方法的目标跟踪脉冲重复频率的选择方法。通过仿真把本文方法和传统的跟踪方法进行了比较,结果表明,本文方法具有跟踪维持性能好、收敛快,跟踪精度高的特点。A new target-tracking algorithm was proposed for airborne fire control radar operating with high pulse repetition frequency （HPRF） in frequency-modulated ranging （FMR） mode. Through multi-hypothesis, the problems of target range estimation and ambiguity resolving were converted to the problems of static multiple model estimation and decision. The method to select the PRF used to track the target was also suggested according to the states of the survived hypotheses. Because the frequency measurements and the ambiguous range measurements are used to estimate the range of the target, compared with the conventional method, the multi-hypothesis algorithm can track target steadily with rapid convergence and high accuracy.
