Abstract
A method to describe and estimate the characteristics of target with micro-motions based on cyclostationary theory is proposed in this study. The radar signal returned from a target with vibration or rotation can be modelled as cyclostationary, and a method based on cyclic statistics is designed to estimate the frequency and amplitude of the vibration or rotation. The experiments showed the performance of the proposed method under different signal noise ratios with simulated radar data.
