1. A non-transitory computer-readable recording medium storing a spectrum analysis program causing a computer to execute:
generating, using an annihilating filter method, first frequency spectrum data from a received wireless signal;
generating, using a frequency spectrum analysis method different from the annihilating filter method, second frequency spectrum data from the wireless signal;
pairing, with each other, frequency values that are closest among frequency values of the first frequency spectrum data and frequency values of the second frequency spectrum data; and
generating, based on a comparison between a first power value at a first frequency in the first frequency spectrum data and a second power value at a second frequency corresponding to the first frequency in the second frequency spectrum data, frequency spectrum data indicating an analysis result, wherein the first power value is used as a power value at the first frequency in the frequency spectrum data indicating the analysis result in a case where the first power value is less than or equal to the second power value, and the second power value is used as a power value at the first frequency in the frequency spectrum data indicating the analysis result in a case where the second power value is less than the first power value.
