The invention discloses a direct interference suppression method and device based on dual-channel disturbance erasure, and belongs to the technical field of optical communication and radar signal processing. The invention provides a physical layer structural suppression scheme for solving the problem that a traditional adaptive filtering method depends on a linear channel relation model and is prone to failure under a complex channel. According to the scheme, a received signal containing direct interference is sent into two optical fiber paths with different dispersion mapping, different time delays and different phase-intensity modulation (PM-IM) response characteristics through an optical power divider, so that the direct signal generates irreversible differential nonlinear distortion in the two paths; and then the two paths of signals are synthesized and output. The process thoroughly destroys the linear correlation between the direct interference and the reference signal, so that the direct interference cannot be modeled and filtered by an adaptive algorithm. And the legal receiving end can construct a reverse compensation structure to recover the signal because of knowing all disturbance parameters. According to the method, the interference suppression robustness and the physical layer security of the system in nonlinear, multipath and other complex environments are fundamentally improved.
