Abstract

Abstract

In a certain observation time duration, the instantaneous frequency of motion target with large acceleration is ambiguous. This case is usually met in flexible-motion target with high velocity. If target has micro-motion, it will cause micro-Doppler modulation which adds in the ambiguous Doppler frequency. In order to extract micro-motion feature of large acceleration target, a parameter estimation method is proposed. Through the ambiguity resolution of Doppler frequency and the estimation and compensation of bulk motion of target, micro-Doppler extraction is achieved. And then, micro-motion period is estimated. Analysis based on simulation and measured data show that the method is suit for micro-motion parameter estimation of large acceleration flexible-motion target.
