基于信号配准的组网信号级融合检测研究

A Study on Signal Level Fusion Detection Based on Signal Registration

针对多雷达的信号级融合检测,提出了一种信号配准方法。在目标搜索阶段利用预处理的匹配表将各雷达信号时空对应,根据预先划分的检测单元进行目标检测,该方法能够减少信号配准时间,排除无用观测值,降低融合中心计算资源消耗;在目标跟踪阶段,利用雷达接收波束重合区间确定信号融合检测区间,能够减少融合中心待处理观测值,更快聚焦至目标。该方法对距离欺骗的有源干扰目标有一定预判性,降低了虚假目标出现的可能,并且能够降低运算量,提高检测效率。

Based on the signal level fusion of multiple radar detection,a method of signal registration is presented in this paper.The target search phase by using the matching table of the pretreatment to the corresponding radar signal in time and space,according to the division in advance detection unit for target detection,this method can reduce the registration time signal,eliminate useless observations,reduce consumption of computing resources fusion center;In the target tracking stage,signal fusion detection interval can be determined by using radar received beam coincidence interval,which can reduce the observation value to be processed in fusion center and focus to the target faster.This method can be used to predict the range spoofing active jamming targets,reduce the possibility of false targets,reduce the amount of computation,and improve the detection efficiency.
