Now the numerical weather forecast plays an increasingly important role on extreme weather forecasting,and the observation data of high resolution remote sensing load is the data needed for data assimilation.However,atmospheric satellite payload microwave radiometer due to the long development cycle,cost and other factors,need the research and demonstration in remote sensing load manufacturing,so the simulation process observation of satellite microwave radiometer remote sensing atmospheric load is significance before the launch,through the simulation of the specified load parameters feasibility analysis can verify the design scheme,the deficiencies can be found in the scheme,so as to improve.Because of the limited size of the antenna,constraints of orbit height,the resolution of remote sensing satellite microwave radiometer are often unable to meet the needs of the application,many studies use algorithm to image processing to improve image resolution for the resolution of the problems.This paper first introduces the principle of microwave radiometer.Then,the simulation and simulation parameters of the remote sensing load of the geostationary orbit are carried out.The simulation parameters are set according to the Founder IV satellite,and the simulation results are analyzed to analyze the characteristics of each band in the geostationary orbit satellites.Then,based on the ATMS load parameters of the orbiting orbit satellite,the observation and simulation of the atmospheric remote sensing load of the polarimeter satellite load microwave radiometer is carried out.After the simulation results are obtained,the simulated light temperature is compared with the ATMS load observation data,and the simulation results are analyzed.Finally,after obtaining the observed brightness temperature,the enhanced image is obtained by using the super-resolution algorithm for observing the bright-temperature image.The use of the super-resolution algorithm,including Backus-Gilbert algorithm and Wiener filter algorithm,the algorithm simulation verification,analysis of the characteristics of the algorithm,while the enhanced image comparison and analysis.
