We have developed a new technique, called quick‐look data analysis, for radio transient searches at the Nasu Interferometer. Quick‐look data, a color map according to the radio source signal‐to‐noise ratio (S/N), were generated spatially and temporally from drift‐scanning data. A steady source appears at the same right ascension with the same color every day. In contrast, transient objects such as radio bursts appear irregularly in the sky, and the resulting map will have sporadic patches. Radio transient WJN J1443+3439 has already been detected using this technique. The quick‐look data were created using processes that we call the fringe‐detecting method and color image creation, which we describe here, and we show actual color images of Cyg A, 3C 48, Mrk 501, and the transient radio source WJN J1443+3439 found in 2005.
