使用BG反演算法细分重建微波辐射计图像

Subdivided Reconstruction of Microwave Radiometer Images with BG Inversion Method

针对传统BG反演算法对微波辐射计图像增强效果有限的不足,提出了改进BG反演算法的新方法——细分重建方法,来进一步提高辐射计图像的空间分辨率。描述了新方法的计算过程,比较了新的方法与传统的BG反演方法在处理上的异同,并使用模拟的数据对这两种方法的性能做了定性的分析和定量的比较,验证了新方法的有效性。

The affection of enhancing the spatial resolution of microwave radiometer images with traditional BG inversion theory is finite. In this paper, a new method subdivided reconstruction which improves BG inversion method to further enhance the spatial resolution is presented. The similarities and differences between this new method and the traditional method are compared in detail. A validation procedure is performed to demonstrate the effectiveness of this new method by using a synthetic image without considering the system errors.
