一种辐射源位置与同源信号到达时差解耦的方法

By decoupling the nonlinear coupling relationship between the radiation source location and the arrival time difference of the same source signal, the location of the radiation source is determined using the location and signal information of the detection equipment. This solves the problem of difficulty in determining the target distance caused by the non-fixed location of the radiation source in passive detection, and realizes real-time target positioning.

AI Technical Summary

Technical Problem

In passive detection methods, when the location of the radiation source is not fixed or the location of the target detection device changes dynamically, it is difficult to update the radiation source location information in real time, making it impossible to determine the target distance.

Method used

By decoupling the nonlinear coupling relationship between the location of the radiation source and the arrival time difference of the same source signal, and using the location of the detection device as the origin of the coordinate system, the distance to the radiation source is calculated based on the direction of arrival and arrival time of the signal from the same radiation source to determine its location.

Benefits of technology

It enables real-time acquisition of radiation source location information in passive detection, and is suitable for situations where the radiation source location is not fixed or uncertain, and for determining the target distance.

Abstract

本发明公开了一种辐射源位置与同源信号到达时差解耦的方法,针对无源探测中确定目标距离需要先确定辐射源位置的问题,利用同源信号的来波方向、到达时间对辐射源位置与同源信号到达时差之间的非线性耦合关系进行解耦处理,从而确定辐射源位置;本发明可利用辐射源直达波信号来波方向、到达时间以及反射同一个辐射源辐射信号的多个目标的反射波信号来波方向、到达时间确定辐射源的距离,从而在无源探测中为确定目标距离提供辐射源位置信息,适用于可利用的辐射源位置不固定或者不确定的场合。
