Summary:The invention discloses a DS/FH frequency-hopping spectrum-spreading data transmission signal capturing method based on long code phase assistance, capable of solving the technical problems of relatively high cost and low efficiency of an existing method for keeping system synchronization for a DS/FH frequency-hopping spectrum-spreading hybrid system. Based on a local oscillator, the following steps are implemented: S100, carrying out carrier stripping on a signal at a set frequency hopping frequency point; S200, calculating code phase shift and Doppler shift of the signal at the current frequency hopping frequency point based on the step S100; S300, realizing synchronization of frequency hopping patterns based on the step S200; and S400, calculating Doppler shift of the signal at all frequency hopping points. According to the DS/FH frequency-hopping spectrum-spreading data transmission signal capturing method, the problem that receivers cannot be synchronized due to inconsistent Doppler shift of different fr
