Problems solved by technology

[0003] H.Xianqiang et al. described the atmospheric correction method adopted by my country's HY-1A / COCTS ocean remote sensing satellite in The atmospheric correction algorithm for HY-1A / COCTS, SPIE Remote Sensing (SPIE, 2005), Vol. 5977. The main defect is that the atmospheric correction process only considers the water-leaving radiation intensity component, and does not consider the atmospheric diffuse transmittance corresponding to the water-leaving radiation polarization component when it is transmitted in the atmosphere. Water radiation information is very important to explore water body components and sea conditions. If the atmospheric correction process is not accurate enough, it will greatly affect the subsequent exploration of related water color components.

Abstract

The invention provides a satellite atmospheric correction method for a multi-angle polarized water color remote sensor. The atmospheric correction method provided by the present invention uses the vector radiation transfer model to construct an index lookup table of atmospheric diffuse transmittance for the linear polarization component of the water-leaving radiation in the water body with medium and low turbidity. After accurate correction, the concentration of suspended particulate matter in water and the distribution of aerosol optical depth, concentration and particle size were obtained accurately according to the linear polarization component of water-leaving radiation. Through the atmospheric correction method provided by the present invention, the image quality of satellite remote sensing detection can be higher, and the detection result is more accurate.

Description

technical field [0001] The invention belongs to the field of remote sensing image processing, and in particular relates to a satellite atmospheric correction method for a multi-angle polarized water color remote sensor. Background technique [0002] The atmosphere is an important factor affecting the quantitative analysis and application of water color remote sensing. In the radiation intensity information received by the top of the atmosphere, atmospheric signals account for about 90%. Therefore, eliminating atmospheric effects is an important prerequisite for determining the accuracy of water color remote sensing analysis. Atmospheric correction of polarization images is of great significance for obtaining real polarization information of water bodies. [0003] In The atmospheric correction algorithm for HY-1A / COCTS, SPIE Remote Sensing (SPIE, 2005), Vol. 5977, H.Xianqiang et al described the atmospheric correction method adopted by my country's HY-1A / COCTS ocean remote se...
