【摘要】 在现代空战战场环境中,复杂的电磁干扰导致雷达对目标的跟踪精度急剧下降。雷达与被动传感器融合使用的必要性日渐显著。本文对在被动传感器和雷达融合下的目标跟踪问题进行了研究,首先研究了雷达和被动传感器的使用逻辑和基于信息需求的雷达控制方法;然后针对基于雷达和被动传感器融合使用支持下的目标跟踪问题,提出了IMM-UKF与TASIMM-UKF双模状态估计算法;最后通过仿真结果分析了此算法的有效性和准确性。更多还原

【Abstract】 The accuracy of radar target tracking was reduced by complicated electromagnetic interference in modern Aerial battlefield,so the combination use of radar and passive sensors is more and more necessary.The problem about radar target tracking supported by combination use of passive sensors and radar was studied in this paper.At the beginning,it showed the using logic of passive sensors and radar and a radar control method based on information requirement;and then IMM-UKF and TASIMM-UKF dual model state estimation algorithm was put forward for the problem of target tracking based on the support of the combination use of passive sensors and radar.At last,simulate result showed the effectiveness and accuracy of this algorithm.更多还原
