Abstract
To address the issue that the characteristics of inhomogeneous media in the high salt-fog marine environment affect the scat-tering attenuation of the lidar system and ensure the detection quality of the lidar system,based on the analysis of the absorption and scattering of the energy of the bird-repelling lidar by the high salt-fog marine environment,a method for suppressing the scattering at-tenuation of the bird-repelling lidar system in the high salt-fog marine environment is proposed.The scattering attenuation situation is determined,and by calculating the echo signal finally received by the receiver,the backscattering coefficient is determined,and the extinction coefficient of the lidar is corrected to suppress the scattering attenuation of the bird-repelling lidar system in the high salt-fog marine environment.The results show that after the application of this method,the extinction coefficient is significantly reduced,all below 0.2 km-1,which reduces the attenuation degree of light intensity per unit distance.At the same time,the detection distance of the lidar is improved.The maximum value of the backscattering ratio after scattering attenuation suppression is 28.62 dB,which can meet the application requirements of bird repelling in offshore photovoltaic fields.关键词
