The invention provides a multi-carrier signal processing method and a related device. The method comprises the following steps: acquiring a first multi-carrier signal; and compensating the first multi-carrier signal according to the channel state information phase difference of the first multi-carrier signal to obtain a second multi-carrier signal, the channel state information phase difference of the second multi-carrier signal being zero, or the phase difference of the second multi-carrier signal being zero. By implementing the embodiment of the invention, the phase difference of the channel state information of the obtained second multi-carrier signal is zero or the phase difference of the second multi-carrier signal is zero, so that the group delay of the second multi-carrier signal is reduced, the signal-to-noise ratio of the second multi-carrier signal is improved, and the user experience is improved. Therefore, the imaging effect can be improved when the passive target or the active target is imaged by
