摘要：

分析了旋转目标的微多普勒特性与微运动参数的关系，指出其微多普勒信号为三参数的正弦调频信号。针对这一信号形式，推导了多分量正弦调频信号的时频分布特性，提出了一种在时频图上检测三参数正弦曲线的Hough变换方法，进而提出了一种基于TFD-Hough(time frequency distribution-Hough)变换的微运动参数提取算法。仿真实验和外场试验数据处理表明了该方法的有效性和鲁棒性。

Abstract:

It is pointed out that the micro-Doppler signature of the rotating target is three parameters sinusoidal frequency modulation (FM) signal by analyzing the relationship of micro-Doppler and micro-motion parameters. According to this signal form, the time-frequency character of multi-component sinusoidal FM is deduced, and a Hough transform method to detect three parameter sinusoidal curve in time-frequency plane is proposed, then a micro-motion feature exaction method based on TFD-Hough transform is provided. The simulation and the real data result show the method is effective and robust.
