基于SystemVue的微多普勒雷达校准信号生成方法
A Method for Generation of Micro-Doppler Radar Calibration Signals Based on SystemVue
摘要
Abstract
Micro-Doppler radar has the potential to facilitate the recognition of pedestrian posture.How-ever,the current generation of approaches to the micro-Doppler radar verification signals has limited effec-tiveness.Accordingly,with prescribed walking posture feature parameters,a novel method was proposed for the generation of micro-Doppler signals via a semi-physical simulation platform.The principles of the micro-Doppler effect were initially elucidated through an analysis of the translational and rotational motions of a rigid body.Subsequently,a pedestrian model was established by simplifying the structure of the pedestrian into 17 interconnecting scattering points,which represented key parts of the pedestrian.Fur-thermore,a SystemVue software-based system for calibrating the micro-Doppler radar has been devel-oped.IQ modulator and Fourier transform were also employed to extract and analyze the micro-Doppler signals generated by the human body model.Then,a micro-Doppler versus time plot for micro-Doppler signals was obtained.During the experiment,the relative error of the pedestrian velocity was no more than 3%,which demonstrated the reliability and effectiveness of the proposed method.关键词
