PROBLEM TO BE SOLVED: To provide a device for detecting a radiowave transmission source capable of easily specifying the place of the radiowave emission source over a wide range. SOLUTION: The radiowave emission source sensing device comprises: the receiving antenna 10 for receiving the radiowave emitted by the radiowave emission source T in 360°azimuth directions; the AD conversion part 40 for converting the digitized receiving signal into the receiving data received by the receiving antenna part 10; the arriving direction estimating part 50 for estimating the direction of the radiowave emission source T in the 360°azimuth direction and the direction of the angle of elevation; the image-processing part 60 for transforming the estimation result of the arriving direction estimating part 50 into the two-dimensional image from the receiving data by the two-demensional MUSIC method; the photographing part 90 for photographing the 360°azimuth directions surrounding the receiving antenna part 10; and the display part for displaying the image captured by composing the two-dimensional image transformed by the image-processing part 60 and the photographed image captured by the photographing part 90.
