Abstract

The micro-motion features of radar targets put forward a new technology method for accurate identification of targets. Firstly using the linear sum of the radial distance of the strong scattering centers, got by taking sample from the echo signal in the wideband radar, the cycle of the micro-motion and the initial phase of the echo signal. Thenthe two-parameters-extended-Hough-transform to the image, the parameters of the rotating scattering center and the sampling signal of the rotating and sliding scattering center. Lastly, using the linear sum and difference of the radial distance of the separated sliding scattering centers and adopting the least square fitting and solving the multivariate nonlinear equation system, the target's micro-motion features and structure features. Simulation results validate effectiveness of the proposed algorithm.

Key words： micro-Doppler; sliding-type scattering center; micro-motion feature
