Abstract
Aerosols such as fog and dust interfere with the backscattering of laser proximity detection, which severely limits its application range. In order to achieve target recognition under aerosol interference conditions, the study of backscattering law is carried out. Based on Monte Carlo simulation method, the model of lidar interaction with aerosol is established, and the time domain characteristics of backscattering of laser radar are simulated. The peak intensity, signal delay and waveform broadening of backscattering echoes under different extinction coefficient (visibility), scattering coefficient and absorption coefficient were studied. The conclusions obtained from the study have certain reference significance for understanding the backscattering effect of aerosol particles, and also have certain significance for the subsequent research of anti-aerosol interference of laser detection.
