Abstract
Mechanical rotation of structures in a target modulates the phase function of radar backscattering, induces frequency modulation on returned signals, and generates side-bands about the target's body Doppler frequency shift. Based on radar backscatter theory and scattering point model, a universal theoretical radar echo model of circle rotation scattering point on arbitrary plane was derived and established, and the equivalence of this model to the one of vibration scattering point was discussed. At last, the availability of the theoretical radar echo model was validated by using two ways. The result of the theoretical analysis and the simulation indicates the effectiveness of the model.
