The Image Processing Technology Of Microwave Radiometer Based On BG Algorithm

Spaceborne microwave radiometer in the ocean and atmosphere remote sensing has an important role, due to antenna size and weight restrictions, spaceborne microwave radiometer spatial resolution is always lower than limit its application, the application for The purpose of the use of microwave radiometer spatial resolution enhancement algorithm to obtain higher resolution images necessary.This thesis describes the application of microwave radiometer and development at home and abroad, through the study of microwave radiometer applications in various fields, we found that microwave remote sensing technology is an indispensable tool in today's society, also found many deficiencies, such as the problem of low spatial resolution. This article is carried out around this issue. To understand the basis of the microwave radiometer introduced two microwave radiometer spatial resolution enhancement algorithm:Image Deconvolution Algorithm and the BG Inversion Algorithm. Which focuses on the BG inversion algorithm, is also the focus of this issue. Spaceborne microwave radiation due to the lack of information images, so you can generate a simulated image of microwave radiation with antenna function for sampling the analog image to get a blurred image sampling, re-use of the BG algorithm for image enhancement processing samples, and were compared before and after on the increase, the results show that the algorithm can enhance the spatial resolution of microwave radiometers. This article also made a BG algorithm more extensive study, that the BG algorithm is extended to the polarization effect in water, in horizontal polarization and vertical polarization on the basis of the algorithm is a simple introduction. Thesis on system indicators:temperature sensitivity and linearity of the system was verified.Finally, the research work of this paper to summarize summary of the research work in this thesis using the algorithm for the next microwave remote sensing image processing, and further expansion in the algorithm based on microwave remote sensing image processing foundation.
