论文摘要
Micro-Doppler签名是一种有效的功能,用于目标识别和微动参数估计。从频率调制连续波(FMCW)雷达以及目标范围和速度的频率调制连续波(FMCW)雷达中提取高频微多普勒签名是本文中考虑的问题。在提议的方法中,快速时间处理可以规避高度多普勒频率扩散的严重混叠。使用范围多普勒(RD)滤波和经验模式分解(EMD)可以有效带外噪声抑制。仿真研究和实验结果介绍了所提出的方法的有效性。
Micro-Doppler signature is a potent feature that has been used for target identification and micro-motion parameter estimation. The extraction of high frequency micro-Doppler signature from frequency modulated continuous wave (FMCW) radar along with the target range and velocity is the problem considered in this article. The severe aliasing of the high micro-Doppler frequency spread is circumvented by the fast time processing in the proposed method. The use of range-Doppler (RD) filtering and empirical mode decomposition (EMD) enables effective out-of-band and in-band noise suppression. Simulation studies and experimental results present the effectiveness of the proposed approach.
