Aiming at the complex and difficult identification of range-velocity deception jamming signals, a algorithm on recognizing range-velocity deception jamming based on space-time-frequency fusion feature is proposed. Firstly, the difference between the real target and the false target is analyzed in the airspace, frequency domain and time domain. Then, according to the feature  difference between the true and false targets in different domains, the space and frequency domain features of the echo points are extracted respectively. Finally, the extracted space and frequency domain features are fused in the time domain, and the two feature fusion methods: pre-accumulation and binary detection are used to determine the range-velocity deception jamming by using space-time-frequency fusion feature. The simulation results show that the algorithm can effectively identify the range-velocity deception jamming.
