Solar radio images in decimeter wave range consist of many complicated components including a disk component, some bright and weak compact sources, and many diffuse features.
Complicated structures combining these various components maybe cause restoration failure when using conventional algorithms.
Furthermore, the images at different frequencies band are pretty different.
Therefore, restoration method for solar radio image is different from other radio sources.
Some image restoration methods were applied and obtained good results on Nancay radioheliograph images and Nobeyama radioheliograph images, and some new methods were introduced into processing these complicated solar radio images in recent years.
For a new radioheliograph with ultrawide frequency band, new image restoration method which can maximize function of telescope is demanded.
Different images could be obtained from the same visibilities data by using different weighting functions in imaging processing.
In this paper, a new restoration method for solar radio image was proposed.
Two images with different weighting functions from the same data are combined in this method.
This restoration method has applied to data processing of Mingantu spectral radioheliograph.
