Review of the Researches on Micro-Doppler Effect of Radar Targets

The micro-Doppler effects of radar targets have attracted great research attention in recent years.The auto target recognition based on micro-Doppler signatures is considered as one of the most potential techniques in radar targets' accurate recognition.The achievements and applications of the micro-Doppler effects of radar targets are reviewed in some aspects such as the concept of micro-Doppler effect,the micro-Doppler analysis and feature extraction,the applications of micro-Doppler effect,and so on.Simultaneously the trends of the technique developments in this field are predicted.
