Abstract: Due to the absorption and scattering of water, the beam energy will attenuate in the process
of propagation, and the laser pulse will be widened, which restricts the detection range and accuracy of
underwater lidar. Based on the application background of underwater weak and small target detection
in turbid water environment, the photon propagation process is simulated by Monte Carlo method, the
Monte Carlo simulation model of underwater photon propagation is established, the echo signal of lidar
under different attenuation coefficients is simulated, the size of laser spot under different attenuation
