The invention discloses a holographic MIMO array multipath channel sensing method and system, and belongs to the field of wireless communication, and the method comprises the steps: S1, carrying out the interference superposition of a reference wave transmitted by a holographic MIMO array plane and a received signal EO1 (x, y) of a user signal reaching a holographic MIMO array unit through a channel, and generating a hologram I (x, y); s2, removing a direct current component and a conjugate component in the hologram I (x, y) in a spatial frequency domain or a time domain to obtain a hologram after interference removal; a corresponding receiving signal EO (x, y) is recovered from the hologram subjected to descrambling; and S3, performing channel state estimation by using the received signal EO (x, y). According to the method for channel estimation based on the information of the power, an economical and efficient novel communication architecture and normal form are constructed, the method is suitable for multi
