英文摘要： The infrastructure of Chinese Spectral RadioHeliograph in CM-DM Range (CSRH) has been completed, and all kinds of principles validation and algorithm testing have been implemented. The hardware part of decimetric wave (CSRH-I) has been built in 2011 as well. These achievement has made International counterparts pay high attention on this project. In this application, we aim to provide data processing and analysis platform for CSRH, and make it play an important role as a new generation of solar radio observation equipment. Based on the layout, structure, location of antenna array and receivers, image reproduction algorithms and parameters optimization methods will be designed and analysised carefully in order to ensure high quality and high-precision results. The very high speed data processing pipeline using distributed storage and GPU parallel technology will be implemented in processing massive data of multi-channels in milliseconds. The results will be shared through the WEB and SSW interface. The platform of data processing and analysis which will be achieved in this project will be installed in the National Astronomical Observatory, integrated with CSRH and support CSRH observation. The results of the project will not only directly apply to the observation on CRSH, but also will be the foundation work for
