PROBLEM TO BE SOLVED: To provide a radio-wave generation source visualization system capable of easily estimating and visualizing radio-wave generation sources even when the radio-wave generation sources are generation sources of radio waves emitted only for a short time. SOLUTION: The radio-wave generation source visualization system is provided with a reception part for simultaneously receiving incoming radio waves at a reference antenna and an array antenna including a plurality of antenna elements; an arrival direction estimating and processing part for acquiring digital data corresponding to signals simultaneously received at the reference antenna and the array antenna, estimating the arrival direction of radio waves through the use of a complex amplitude value of the digital data by radio holography, and generating wave-source images; and a display part for combining an environment image acquired by photographing the environment of a section estimated as a radio-wave generation source with a wave-source image and displaying them.
