　　对典型目标的进动和翻滚给出了统一的数学表达式，分析了不同的微动形式对雷达回波调制的散射机理，提出了基于雷达一维距离像的能量起伏特征和径向长度特征的微动识别新方法。使用物理光学和物理绕射理论的高频方法仿真了锥体进动、柱体翻滚和非理想球体翻滚的宽带雷达回波，利用仿真数据，完成了高分辨成像和相关特征提取。研究结果表明，三种不同的微动目标的距离像能量起伏特征和径向长度特征差异明显，可以将两种特征联合使用，用于微动识别。

In this paper, a unified mathematical expression is given for typical target’s procession and rolling, the scattering mechanism of various micro-motion forms modulating on radar echoes is analyzed, and a novel identification method for micro-motion with characteristics of energy fluctuation and radial length is proposed, based on radar one-dimensional range profile. By using the HF method of physical optics and diffraction theory, the wideband radar echoes of conical procession, cylinder rolling and non-ideal sphere rolling are simulated, based on which, the correlated characteristics extraction and high resolution profile are performed. Study findings indicate that the characteristics of range profile energy fluctuation and radial length of three types of different micro-motion targets vary clearly, and two types of characteristics can be combined for the use of micro-motion identification.
