惯导误差下分布式雷达多目标空间配对算法

Multi-target paring algorithm for distributed radar with INS error

当分布式高速雷达组网平台存在大的惯导误差时,要实现多目标环境下的组网信号级融合检测,必须解决多目标的空间配对问题。因此,提出了一种利用目标距离信息,结合多路径信息冗余特点的方法来实现多目标空间配对。首先,从理论上推导了判别目标正确配对的表达式,并分析了表达式结果与目标配对情况的对应关系。然后,根据当前目标配对情况设计出相应的目标配对方法。最后,仿真结果验证了该目标配对算法的有效性。

This article studies multi-target spatial pairing methods with inertial navigation system （INS） error, which exists in the distributed high speed radar network. In order to realize the signal level fusion de- tection of multiple targets, it is necessary to solve the multi-target paring problem. Therefore, a method u- sing target range information and multi-path information to achieve multi-target matching is proposed. First of all, the formula of the correct multi-target pairing has been derived theoretically, and the correspondence between the result of expressions and the target pairing status is analyzed. Then, according to the multi-tar- get pairing result, the corresponding pairing method is designed. Simulation results verify the effectiveness of the proposed algorithm.
