我国新一代厘米—分米波太阳射电日像仪(中文 Spectral Radio Heliograph,CSRH)已经进入了设备调试阶段,对数据系统的建设有迫切的要求。如何快速、可靠地实现数据的可信处理,实现一个可供调试及未来使用的数据处理系统是一项十分重要的工作。以射电天文软件包CASA为对象,分析探讨了CASA混合软件开发模式和二次开发利用的可能性,系统阐述了利用Python开发前台,后台调用C++语言的混合编程方法,进而讨论分析了利用混合编程扩展CASA功能以满足太阳射电日像仪应用需求的方法。本方法具有较强的针对性,对我国其它天文新设备数据处理软件系统的开发具有一定的借鉴作用。

The new generation spectral radioheliograph of China (CSRH) working in the wavelength range from centimeters to decimeters has entered its testing stage. It becomes urgent to study efficient and reliable approaches of instrument calibration and observational data processing for the CSRH to facilitate its development. In this paper, in order to meet the need of establishing a data processing system that can be used for current tests and future observations with the CSRH,we discuss development modes for the CASA (Common Astronomy Software Applications) software system and explore approaches of secondary developments of the system. We propose a hybrid programming method combining the Python and C++ for developments of software applications. We discuss the details of this method,which for a software application uses the Python for developing the front stage and makes C + + routines called in the back stage. We further describe a practical approach to expand the functions of the CASA based on the hybrid programming. In summary,our method can contribute to the research and development of the CSRH ; furthermore, it can serve as a reference for the research of data processing software systems for other new astronomical telescopes in China.
