  • Precession characteristic is one of the significant properties for cone-shaped spatial target recognition. To analysis the micro-Doppler feature induced by precession, a method based on the generalized S transform was proposed. In the mathematical model of coning precession, the multi-coordinate system with the same origin was used to simplify model structure and computation complexity. Then the theoretical expression of the micro-Doppler due to precession was derived. The validity of the model was confirmed by computer simulation. Based on simulated radar data for precession cone, the generalized S transform was introduced and used to analyze the micro-Doppler feature in the condition of different signal to noise ratio (SNR). The experimental results in the joint time-frequency domain show that the method has large advantage in the time-frequency resolution, and is robust for the complicated micro-Doppler signal at low SNR.
