Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention is described in detail, as figure 1 As shown, the details are as follows:
[0022] 1. If figure 2 Deployment system equipment shown (taking ground deployment as an example). Deploy the three receiving auxiliary stations L120, R130, and H140 around the central receiving station C110 in a certain way (star, T, etc.), and deploy the central station on the radar (or interrogator) Around 100, the baseline length 210 is controlled within several kilometers. Select the connection mode between sites according to the actual situation, such as optical fiber or wireless. The above-mentioned receiving stations (central receiving station and receiving auxiliary station) can not only use the radiation signal of the target but also use its reflected signal to locate the target; each receiving station adopts a short baseline (the length of the baseline is within a few kilometers, and the typical value is 0.1km~ ...
