Claim 4:
5. The radio wave feature value computation apparatus according to claim 1, the at least one processor is further configured to execute the instructions to select a fixed signal output from one specific individual within a fixed signal of the received communication wave, wherein
the at least one processor is configured to execute the instructions to designate the information-1 section and the information-2 section within the selected fixed signal,
in the information-1 section signal processing, the at least one processor is configured to execute the instructions to perform Fourier transform on the information-1 section designated within the selected fixed signal, and
in the information-2 section signal processing, the at least one processor is configured to execute the instructions to perform Fourier transform on the information-2 section designated within the selected fixed signal,
the at least one processor is further configured to execute the instructions to perform, regarding the selected fixed signal, processing of averaging, for each frequency bin, feature values computed for N times, where N is any natural number.
