Embodiment
[0038] The passive sensor network detection method of the present invention mainly includes two parts: static removal of "ghost spots" and dynamic removal of "ghost spots":
[0039] Static to "ghost spot"
[0040] Such as figure 1 As shown, according to the principle of side angle cross positioning, it is assumed that the position of the radiation source (target) is (x, y), and the coordinates of platform 1 are (X 1 ,Y 1 ), the coordinates of platform 2 are (X 2 ,Y 2 ), and the measured azimuth angles are θ 1 , θ 2 , then the coordinates of the target can be expressed as:
[0041] x = Y 2 - Y 1 + X 1 tan ...
