Abstract

This article studies the micro- Doppler characteristics of chaff cloud scatter based on the chaff filaments dispersion experiments. This paper highlights the extraction method of micro-Doppler features using the Empirical Mode Decomposition method incorporated with time-frequency analysis method. In order to extract the characteristics, the scattering signal is decomposed into a set of intrinsic-mode functions that are represented at different scales. The components are then reconstructed and analyzed by adopting the Short-Time Fourier Transform. After the separation of the Doppler frequency of the unexpanded chaff cluster radar return, the micro-Doppler frequency and micro- motion parameters of chaff filaments are estimated. The results of the experiment show that this extraction method has been successfully adopted to obtain the micro- Doppler features of chaff filaments. And a conclusion has been proved that the period of micro-Doppler frequency is determined by the period of chaff filaments vibration.
