| 摘 要： | 针对传统无源数据关联算法存在算法复杂、计算量大等缺点，提出了一个能够反映辐射源特征参数信息与目标运动状态参数信息相结合的无源关联算法流程。该算法首先定义基于目标运动状态参数和辐射源特征参数的多维可变跟踪门，然后运用模糊多门限思想，将测量与目标的关联概率来替代概率关联算法中可行联合事件概率的计算。仿真结果表明该算法计算量小，跟踪准确度高，尤其适用于复杂环境下近距离、交叉运动目标等典型情况。

| Abstract: | Aiming at the defect of traditional passive data association algorithm, a new passive association algorithm flow which can reflect the information of transmitter parameters and target moving status parameters is proposed. A multi dimensional tracking gate based on the information of transmitter parameters and target moving status parameters is defined in this algorithm. Then fuzzy multi gate thinking is exerted which used the associated probability with target and its measurements for calculation instead of the feasible associated incident probability in the association algorithm. The simulation indicates that this algorithm is possessed of the merits of less computation time and high accuracy in passive tracking, and especially is suited for representative instances such as short distance, cross moving targets in complex circumstances. |
