When the infrared polarization system detects a sea marine target through a long distance,the scattering of the ocean aerosol deteriorates the imaging quality seriously,and the scattering of the depolarization causes the target and the background to be indistinguishable.In this paper,based on the aerosol Mie scattering model,the scattering depolarization model is deduced.Then,according to the particle distribution of different aerosols,a correction model of scattering depolarization is established on the foundation of the simultaneous correction of the atmospheric transmittance and the infrared polarization system.Aerosol scattering is studied on the influence of different scale factors,different scattering angles,and different scattering light vector.According to the experimental images,the quality of the images obtained after correcting by the scattering correction and the infrared polarization system proposed in this paper has been significantly improved.The method can better correct the influence of atmospheric aerosol scattering on infrared polarized light,and more accurately reflect the polarization characteristics of the target and the background.Therefore,infrared polarization scattering correction is of great significance for target detection and recognition.
