| 摘 要： | 针对组网无源雷达多目标跟踪问题，提出一种新的变数目多目标跟踪算法，实时估计目标数目与多目标状态．算法采用多站集中式融合策略解决无源观测的不完全性问题，采用最小二乘算法构造伪位置观测解决无源观测的非线性问题．针对变数目多目标跟踪问题，利用随机集理论将多目标状态与观测构成随机有限集，通过高斯混合概率假设密度滤波递归计算多目标状态随机有限集的后验强度，实时得到目标数目及其状态的估计．算法引进最小二乘算法估计出候选目标点进行数据关联，解决了无源观测线较近时无源数据关联精度下降问题．仿真实验验证了该算法的有效性．

| Abstract: | A new recursive algorithm is proposed for jointly estimating the time-varying number of targets and their states through passive radar measurements.Firstly,multi-sensor central fusion scheme is adopted to improve the weak observability for passive systems.Secondly,the least square method is embedded to calculate pseudo-location measurements by which the nonlinearity is solved.Thirdly,for the scenario of the time-varying target number,the new approach involves modeling the collections of targets and measurem... |
