This invention proposes a multi-station radar high-speed target detection method based on axis rotation and dual-core Radon cubic phase. The implementation steps are as follows: range travel compensation is performed on the signal after second-order Keystone transform based on an improved axis rotation method; Doppler diffusion compensation is performed on the potential target signal based on the dual-core Radon cubic phase function; the data correlation results between the measured values ​​and the target are calculated, and the multi-station radar high-speed target detection results are obtained. In the range travel compensation of the second-order Keystone transform signal, this invention only rotates the fast time axis of each range block signal, improving the two-dimensional parameter search for range and velocity into a one-dimensional rotation angle search, thus reducing the computational load; the Doppler diffusion compensation of the potential target signal based on the dual-core Radon cubic phase function transforms the high-dimensional parameter search into an instantaneous frequency change rate search, improving detection efficiency and detection probability.
