基于时间反演的多目标信号自适应配对方法

信号配对是多目标无源探测需要解决的首要问题，若目标辐射信号具有相同特征，采用传统的信号分类配对方法难以实现有效的配对，从而产生虚假目标。本文提出了一种基于时间反演的多目标信号自适应配对方法，通过收发信道的匹配滤波特性，在时域和空域上对干扰信号进行滤除，使目标信号在探测空间中自适应地形成时空聚焦区域，并在焦点处反演出目标辐射波形，自适应地实现了接收信号的配对。仿真结果验证了本方法的正确性和实用性。

An adaptive signals pairing method of multi-target based on time reversal

Signals pairing is the chief problem of multiple targets passive detection, and if the signals radiated from targets have the same features, it is difficult to realize signals pairing effectively using the traditional classification and signals pairing method which are prone to obtain false targets images in this situation. This paper proposed an adaptive signals pairing method based on time reversal, taking the advantage of matching filter characteristics of receiving and sending channel, filtering out interfering signals in time domain and spatial domain, focusing the target signal adaptively at specific moment and location in the detection space. The time reversal waveforms of targets appear in the focusing spots, and mate pair of receiving signals. The simulated results prove the correctness and applicability of this method.
