[0058] combine figure 1 , figure 2 with image 3 As shown, step S2 is described in detail. According to an embodiment of the present invention, the target device D receives the spacecraft A through the k-way communication antenna (the first communication antenna B 1 , the second communication antenna B 2 , ..., the kth communication antenna B k ) The forward signal chip sent by . see Figure 4 , in this embodiment, the target device D automatically sets the correlation length of the received forward signal chip to be an integer multiple of the frame length of the forward signal chip.
[0059] Wherein, step S2 also includes the following steps:
[0060] Step S21, in this embodiment, in the target device D, compare the received peak value of the forward signal chips sent by the k-way communication antennas bit by bit with the threshold set in the target device D, and obtain The first peak value greater than the threshold b 1 .
[0061] Step S22, in this embodiment, the...
