Abstract: Based on wideband linear frequency modulation waveforms model for high velocity target, the theoretic expression of high velocity target echo is obtained and the qualitative analysis is given. After analyzing the velocity influence, a high efficiency and practical velocity compensation method is presented. The method is not only valid and robust, but also needs less computing cost. In order to evaluate the compensation effect, information entropy and normalized square deviation are used. The accuracy requirement for compensation is also presented. Finally, the simulated data demonstrate the validity of the proposed method.
