| Research Abstract |
In this study, wide-field drift scanning surveys were conducted repeatedly. The radio flux density was monitored and the radio atlas was made. By observation, I detected the variable radio sources. In addition, data analysis process was established. Evaluation methods were made clear about the reliability of the transient signal and the flux variability. The establishment of the data analytical technique was a problem, because the time series interference fringe data is a unique format. I accomplished improvement about reliability and the quick response for the analysis result. The radio atlas is used as template data to evaluate flux variability. Approximately 680 strong interference fringes are included in a radio atlas and this result shows enough the performance of the FFT processor introduced in previous studies.
