AI Technical Summary
In complex and ever-changing electromagnetic environments, it is difficult to determine the location of a radio source by relying solely on the direct wave signal direction estimation from a single radio source, the signal direction estimation from randomly distributed targets, and the signal arrival time difference estimation.
By setting the location of the passive detection device as the origin of the coordinate system, and using the direct wave direction estimation of multiple radio radiation sources and the signal direction of arrival estimation of different targets reflected by the signals, combined with the signal arrival time difference estimation, the arrival time difference of the signals reflected by different targets corresponding to each radio radiation source is demixed to determine the location of multiple radio radiation sources.
It enables accurate determination of the location of multiple radio radiation sources when the radiation source location is not fixed or uncertain and the target location is randomly distributed, and is suitable for target detection and positioning in complex electromagnetic environments.
