摘要/Abstract

摘要： 为实现对激光探测回波微多普勒效应的物理仿真,建立了单点运动的微多普勒效应的数学模型。提出了基于可控振动器和基于声光调制器(AOM,acousto-optical modulator)的两种激光散射回波微多普勒效应物理仿真方法,并分别搭建了原理实验系统。实验结果表明两种方法可以实现对激光回波频率的调制,基于可控振动方案仿真方案优点在于模拟结果更接近实际情况,但频率调制范围较小,而基于声光调制的方案频率调制范围大,但是多个运动叠加较为困难。

Abstract: In order to realize the physical simulation of the micro-Doppler effect of laser detection echo, a mathematical model of micro-Doppler effect for single-point motion is established. Two physics simulation methods for laser scattering echo micro-Doppler effect based on controllable vibrator and acousto-optical modulator are proposed, and two experiment systems are set up. The experimental results show that the two methods can achieve the modulation of laser wave echo. The advantage of the simulation scheme based on controllable vibration is that the simulation results are closer to the actual situation, but the frequency modulation range is smaller, while the scheme based on acousto-optical modulation has a large frequency modulation range, but it is difficult to overlap multiple motions.

Key words: micro-Doppler effect, acousto-optical modulator, physical simulation methods, target recognition
