Abstract

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.
