Abstract：Interference forwarded by intermittent sampling based on digital RF memory is a new type of coherent interference that can achieve both suppression and deception effects,constituting a serious threat to radar target detection.Aimed at the problem that the interference is of forwarding by intermittent sam-pling in which radar transmission signal is linear frequency modulation signal,a suppression technique based on YOLOv8 algorithm is proposed.Through STFT used for time-frequency analysis,and the im-proved YOLOv8 algorithm used to identify interference features in the enhanced time-frequency distribu-tion grayscale map,a filter is designed in the time-frequency domain to suppress the interference signal.The simulation comparison experiment results show that this method is good at interference suppression effect,which is low in signal-to-noise ratio,weak in interference,and is good at coordination with multi-point source.Compared with the other methods,this method solves the problem of overlapping interfer-ence and target time-frequency distribution that cannot be recognized,and is robust.
