Abstract: An electromagnetic wave discrimination device according to the present invention discriminates electromagnetic waves, and includes an acquisition section, a feature quantity calculation section, a similarity calculation section, a classification section, a discrimination section, an output section, and a storage section. The acquisition section receives communication signals of a predetermined frequency, and samples waveform data of the communication signals every predetermined time to obtain sample data for each predetermined time. The feature quantity calculation section calculates amplitude feature quantities for each predetermined time, based on the sampling data for each predetermined time. The similarity calculation section calculates degrees of similarity with respect to the amplitude feature quantities for each predetermined time.

Abstract: Disclosed is radio monitoring apparatus which includes a radio station distinction unit, a direction measurement unit, a transmission source location estimation unit and a transmission source location classification unit. The radio station distinction unit outputs radio station distinction information for uniquely discriminating a radio station that is a transmission source of a transmitted signal from a received signal. The direction measurement unit measures an arrival direction of the transmitted signal. The transmission source location estimation unit estimates a location of the transmission source from results of the direction measurement and outputs an estimated location as transmission source location information. The transmission source location classification unit relates the radio station distinction information and the transmission source location information and outputs them.
