Method for resisting same-frequency interference based on reflection amplification surface

The invention discloses a method for resisting co-frequency interference based on a reflection amplification surface. The method comprises the following steps: S1, constructing a communication system for resisting co-frequency interference based on the reflection amplification surface; the communication system comprises a transmitter, a receiver, at least one jammer and an amplification reflection surface. S2, a reference power threshold value L of the jammer is given, and emission coefficient design is carried out according to the size relation between the emission power PI of the jammer and the reference power threshold value L: (1) if the emission power PI of interference is greater than or equal to the threshold value L, namely L is less than or equal to PI, a reflection coefficient is designed based on interference suppression ratio minimization; and (2) if the interference transmitting power PI is less than a threshold value L, namely L is greater than PI, designing a reflection coefficient based on sys
