Paper Abstract

The effective attenuation coefficient of underwater target signals and that of backscattered signals are considered same in the present discuss. By the experiments and simulations of underwater target lidar signals, it is found that they are different. A new Monte Carlo method is introduced in the paper, the scattering phase function is approximately by a distorted Henyey-Greenstein (H-G) function, and the expression of the scattering angle (theta) is obtained from H-G function. The calculation efficiency of this method is improved five times than the traditional Monte Carlo method. Various sizes of the target are simulated in the paper. From the calculation results it is concluded that the effective attenuation coefficient of underwater target signals is larger than that of backscattered signals.
