[0041] The following examples describe the present invention in more detail:
[0042] figure 1 It is a schematic diagram of the synchronous signal structure of the present invention. where f 0 Is the carrier frequency, and k is the modulation frequency of the chip signal. It can be seen that the synchronous signal is composed of three chip signals, the length of the first chip signal is equal to the length of the third chip signal, and their frequency change rates are the same, the length of the second chip signal is the first 2 times the length of the segment cut signal, and their frequency change rates are opposite.
[0043] The synchronous signal of the present invention has two optional frequency change forms, figure 2 It is a schematic diagram of the first frequency change of the synchronization signal in the present invention. where f 0 is the carrier frequency, B is the FM bandwidth of the synchronization signal, and T is the time length of the synchronization si...
