在射电干涉阵的大视场成像中，W-projection和W-stacking是两类主要成像方法，本文对这两种成像方法进行了并行实测研究。首先分析了两种成像方法的基本原理框架，在此基础上对两种成像方法并行实现的关键因素进行讨论和分析。利用已经校准的射电干涉阵观测数据对两种成像方法基于射电天文模拟、校准和成像库（Radio Astronomy Simulation, Calibration, and Imaging Library, RASCIL）分别进行并行策略研究和并行计算实验。通过对并行计算时间、并行效率和并行资源配置模式的分析，得到了两种成像方法基于RASCIL（https://gitlab.com/ska-telescope/external/rascil）的并行计算性能，结果表明，两种成像方法都适合采用Strong Scaling的并行资源配置模式进行并行计算，基于RASCIL的W-stacking并行计算还有比较大的性能提升空间。 

W-projection and W-stacking are classical wide field imaging methods in radio interferometry. In this paper, the parallel computing implementation of these two imaging methods is carried out. First, the basic principle of the two imaging methods is analyzed, based on which the key factors for the parallel computing implementation of the imaging methods are discussed. The parallel computing experiments are carried out based on RASCIL for these imaging methods using calibrated radio interferometry observation data. The performances of the two imaging methods parallel computing are obtained by analyzing the parallel computation time, as well as the parallel efficiency and parallel resource configuration. The results show that both imaging methods are suitable for the parallel computing configuration of Strong Scaling, while the parallel computing of W-stacking based on RASCIL has a great potential for performance improvement.
