The invention provides a tunnel wall back defect anti-interference detection method and device and related equipment, and the method comprises the steps: determining one echo signal as a target signal after responding to a group of echo signals obtained through a receiving antenna, and determining an adjacent signal adjacent to the target signal; wherein one group of echo signals are formed by transmitting and reflecting electromagnetic signals excited by the excitation antenna behind the tunnel wall after the bearing device of the receiving antenna moves a set distance every time; performing continuous wavelet transform on the target signal and the adjacent signal, and determining the wavelet coherence of the target signal and the adjacent signal according to a transform result to obtain a coherence result; and inputting the coherence result into a trained region-based convolutional neural network which takes the residual network as a backbone network, so as to judge whether a defect exists or not and determ
