Abstract

The theory of the micro-Doppler (m-D) effect in frequency-stepped chirp signal is studied

and the causations of the range profile’s migration and wrapping are analyzed.The m-D effects induced by rotation and vibration are discussed in detail and the analytical expressions of the m-D signatures in the range-slow time plane are deduced.The algorithm for extraction of m-D signatures is proposed which is based on the Hough transform and time-frequency analysis.The implementations of the algorithm under condition of different rotating/vibrating frequencies and radii are discussed.Simulations are given to prove the validity of the theoretical analyses and the proposed m-D extraction method.
