When radar is used to track the maneuvering target under speed deception interference, there are many problems such as many false trajectories, hard discrimination of true-false target, and real target tracking instability. In view of these problems, this paper puts forward the speed interference identification method based on velocity estimation radial projection and motion state count delay under multiple false target deception interference. Firstly, the dual-channel maneuver detection method combining velocity measurement and position measurement was used to ensure the accuracy and timeliness of model switching under speed deception interference. Then, the method of motion state count delay was used to determine the time of tracking stability after target model switching; Finally, the test statistics using velocity estimation radial projection based on position information was used to identify the speed deception. The simulation results show that the algorithm has good robustness.
