摘要
在主/被动雷达双传感器目标跟踪背景下,针对IMM算法的计算量大,提出一种基于变结构多模型思想的LMS2UKF分布式融合算法。该算法将LMS算法和UKF滤波算法结合进行矩阵加权融合。与IMM2UKF算法进行仿真比较,结果表明在相同情况下,本算法有较好的稳定性和较好的定位精度。
A data fusion algori tracking in allusion to the weighted of LMS and UKF. IMM' s thm dis using LMS-UKF is presented based on active/passive radar target advantage of computation. The algorithm is integrated by arrays Compared with the simulation of IMM-UKF algorithm, the approach possesses better stability and higher locating precision in the same condition.
