The invention discloses a spread spectrum signal real-time capturing method, a spread spectrum signal real-time capturing system and a medium, relates to the field of large-frequency-offset high-dynamic spread spectrum signal capturing, and solves the problem that the correlation capturing gain is low under the large-frequency-offset condition in the existing time domain sliding correlation capturing technology. Multiple paths of sample point signals with single symbol rates are obtained; performing segmented accumulative sliding correlation operation processing on each path of sample point signals and a local sequence to obtain multiple paths of correlation peak values of the multiple paths of sample point signals after the sliding processing; according to the method, in combination with a segmented cumulative sliding correlation synchronization method and a multi-path capture judgment strategy, through certain resource consumption balance, while the signal correlation capture performance is ensured, the cap
