摘要：
In this paper, a rotor rotation speed estimation method is studied. Firstly, the radar rotor micro motion echo model of the wideband frequency modulated continuous wave (FMCW) is established; then, the echo matrix is transformed into a vector, and the rough estimation of the speed is estimated by coherent integration. Secondly, the real-valued inverse Radon transform (RIRT) algorithm is used to estimate the precise rotor rotation speed based on the theory of minimum image entropy. The proposed method improves the estimation accuracy by coherent and non-coherent integration respectively. The simulation results and the measured data verify the feasibility and effectiveness of the proposed method.
