LFM雷达对高超声速目标的数据关联研究
Multi-radar Data Association of Hypersonic Target by LFM Radar
摘要
Abstract
As a typical multi-radar data association metrics,the association method,which is based on the chi-square statistic metrics,is an effective way used for multi-radar data association in the current information fusion fields.It is found that,however,the correct probability of multi-sensor data association decreases as the radar measurement error decreases,when the target moves in a hypersonic way.In view of the strange phenomenon,the data association model,which is based on the chi-square statistic metrics,is established firstly by the linear frequency modulated radar.Then the influence of target hypersonic movement on multi-sensor data association is further discussed,and the conclusion is that the associated judgment function (subjected to the non central chi square distribution) is contradicted against the existing associated judgment threshold (subjected to the chi square distribution).Finally,the strange phenomenon above,which is proposed in this paper,is explained by using the statistic theories,and an important conclusion is correspondingly drew that the existing data association approaches,which are based on the chi-square statistic metrics,have a great disadvantage on multi-sensor data association of hypersonic target.Simulation results show that,the happening of the strange phenomenon above is reasonable,when the target moves in a hypersonic way.关键词
