Radiation scattering effects in the processing of optical quantitative remote sensing data

Aerospace optical remote sensing is an effective information technology that retrieves physical characteristics of ground objects. With the development of multi-mode payloads and the fusion of multi-source information in spaceborne remote sensing technology, the demand for quantitative and accurate information has raised a series of new issues on information chain technology, and it has also shown great prospects for remote sensing applications. Optical remote sensing image is the basic carrier of feature information. The effect of remote sensing applications largely depends on the image quality. Therefore, improving the imaging quality is of great significance for remote sensing applications. In this letter, the scatter radiation transfer process of the imaging system has been analysed; working principle of scattering imaging in the earth observation process has been introduced, the influence of scatter radiation transfer on remote sensing image quality has been discussed, and the factors of image radiation accuracy has been specified.
