中文摘要：
分布式干扰下,目标的检测概率降低,造成了航迹寿命短,雷达不能对目标进行连续地跟踪。针对上述问题,本文提出了分布式干扰下雷达网多假设跟踪方法。首先利用基于空间距离差的鉴别方法对干扰进行鉴别,鉴别为分布式干扰后,再对干扰功率进行估计,通过构造检测概率改善因子实现了检测门限自适应选取,提高目标的检测概率,最后进行基于数据压缩的多假设跟踪处理。仿真结果表明,此种方法改善了目标的检测概率,提高了航迹寿命,具有较好的对抗分布式干扰效果。
英文摘要：
Under the distributed jamming,the detection probability of target decreases and it makes track unstable and brings down the track lifetime.In order to deal with the above problem,the multi-radar MHT algorithm is proposed.Firstly,distributed jamming is discriminated by range difference.Secondly,jamming power is estimated and the improvement factor is constructed to increase the detection probability.Then target states are estimated by MHT algorithm based on data compressing.The simulation results show that the algorithm can increase the track lifetime and has good performance on anti-jamming and is significance in practical application.
