基于动态滤波重采样的星载微波辐射计观测亮温方法
A spaceborne microwave radiometer method for brightness temperature measurement based on dynamic resampling
摘要
Abstract
The brightness temperature obseration using spaceborne microwave radiometers was studied,and a new method for brightness temperature obervation using the dynamic resampling based on the Backus-Gilbert (BG) method was developed to solve the commonly adopted steady resampling method's problem of no observation of geometrical changing.This method considers the observation of geometry changing in both the north-south direction and the east-west direction,and uses a linear interpolation method to realize the filter template's real-time updating to realized the dynamic resampling.Its simulating test and the real experiment using the data from an advanced microwave scanning radiometer for earth obseration (AMER-E) were conducted,and the results indicate that this method's fitting error is less than the common steady resampling method and has a higher computational efficiency as well as a good potential for applications.关键词
