An electromagnetic wave identification device includes a detection section for detecting an electromagnetic wave signal which is output from an antenna for detecting electromagnetic waves and whose level is equal to or greater than a predetermined level; a measurement and record section for recording and storing the detected electromagnetic wave waveform data; and an analysis and evaluation section for receiving the recorded and stored electromagnetic wave waveform data, normalizing the electromagnetic wave waveform data by an maximum amplitude value to obtain normalized data, and determining whether or not the received electromagnetic wave is a direct wave by reference to the normalized data. The analysis and evaluation section determines whether or not the received electromagnetic wave is a direct wave by obtaining a kurtosis from a histogram of amplitude values of the normalized data and determining whether or not the kurtosis is equal to or greater than a predetermined threshold, or by obtaining a normal probability plot from the normalized data and determining whether a value of the normalized data at a predetermined probability is equal to or greater than, or equal to or less than, a predetermined threshold.
