Multiple Hypothesis Track Algorithm for Airborne Fire Control Radar with HPRF in FMR Mode

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.
