| 摘 要： | 基于MIMO雷达系统,建立了单频信号体制下目标部件旋转、振动的微多普勒效应的数学模型。与传统单基雷达系统相比,当选取的观测雷达组合不同时,得到的旋转微多普勒正弦曲线的幅值、初始相位均不相同,而振动微多普勒正弦曲线的初始相位不变,只有幅值改变。仿真实验验证了理论分析的结果,从而为MIMO雷达系统的微动特征提取及目标识别提供了理论依据。

| Abstract: | Based on the MIMO radar system with single frequency signals, the mathematical models of micro-Doppler effect induced by rotation and vibration parts of target are established. Compared to the traditional monostatic radar system, the amplitude and initial phase of micro-Doppler curves induced by rotation vary with different selections of observing transmitting/receiving radar pairs. In case of vibration, only the amplitude of micro-Doppler curves varies, the initial phase keeps the same value. The simulation results validate the theoretical conclusions, which provide theoretic support for micro-motion feature extraction and target recognition in MIMO radar system. |
