Simulation and analysis of oceanic LIDAR signals

Abstract

The transmission model of underwater photons is established by Monte Carlo simulation to simulate laser detection of objects at a certain distance in the marine environment, and the effects of varying the transmission distance of 10m, 15m, 20m, 25m and the effect of varying the attenuation coefficient of the water body, the asymmetry factor, and the size of the receiving surface on the echo signal at 20m are simulated. The simulation results show that: the larger the transmission distance, the more serious the echo signal distortion and the greater the relative weight of backscattering; the more turbid the seawater, the more unfavorable the effective signal reception; the larger the asymmetry factor is, the better the signal is; increasing the size of the receiving surface can effectively improve the intensity of the echo signal.
