Abstract
An interference source hunting method of hunting for an interference source of electromagnetic waves while moving between multiple measurement points, includes the steps of acquiring strength information of electromagnetic waves, estimating a distance from the measurement point to the location of the interference source, based on the strength information, calculating a first presence probability that the interference source is present at each position, based on whether a distance from the measurement point to the position is within the distance, updating second presence probabilities acquired in hunting in the past, based on the first presence probabilities, determining a position obtained by moving, by a predetermined distance, the measurement point toward a position with the second presence probability higher than the second presence probability at the measurement point, as a new measurement point, and determining, in a case where a size of an area in which each of the second presence probabilities is greater than or equal to a predetermined value is less than a predetermined value, that the location of the interference source is within the area.
