    As it is impossible to predict when and where transient sources will appear, it is necessary to monitor as large an area as possible, and also as often as possible to survey these sources. Recently, full time wide-field survey radio interferometer at 1.4GHz, which consists of eight 20-m diameter spherical dish array, has been constructed in Nasushiobara, Tochigi prefecture, 160km north of Tokyo. Observations are ongoing and a great amount of data is constantly being obtained. However, analyzing this data was a very slow and time-consuming process, which sometimes took several weeks or more for the one-week data. To address this problem, we developed software to facilitate the analysis of the data, which was created in C++ language. All of the preparations for surveying transient sources are completed at the present time. Here we report the automatic analysis software for searching transient sources.
