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 detection of multiple targets,it is necessary to solve the multi-target paring problem.Therefore,a method using 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 co...
