Claim 6:
7. An interference evaluation apparatus configured to evaluate, over an area, radio-wave interference that occurs between a first radio station and a second radio station, comprising
a processor; and
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:, acquire information indicating topographic cross-sections of respective azimuths centered about the first radio station, and distinguish each topographic cross-section into a segment in which there is visibility from the position of the first radio station and a segment in which there is no visibility from the position of the first radio station; and specify a position at which a desired interference amount is reached based on a distance between the first radio station and the second radio station in a segment distinguished as having visibility from the position of the first radio station, and specify a position at which the desired interference amount is reached by evaluating the radio-wave interference for each square of an evaluation target region segmented into squares in a segment distinguished as having no visibility from the position of the first radio station.
