Claim 18:
19. An interference detection method for detecting an interference between feeder links of plural movable aerial-staying type radio relay apparatuses, each of the communication relay apparatus including a relay communication station that relays a radio communication of a terminal apparatus, the interference detection method comprising:
storing position information of plural gateway stations that respectively perform a radio communication with the plural communication relay apparatuses;
acquiring position information on current positions of the plural communication relay apparatuses;
generating plural feeder-link model elements with respect to the plural communication relay apparatuses based on the position information of the plural communication relay apparatuses and the position information of the plural gateway stations, each of the plural feeder-link model elements combining a feeder-link receiving point corresponding to a position of the communication relay apparatus, a feeder-link transmitting point corresponding to a position of the gateway station, and a line segment connecting the feeder-link receiving point and the feeder-link transmitting points to each other in a three-dimensional space model; and
determining an occurrence of interference between the feeder links based on distances between the line segment and the feeder-link receiving point among the plural feeder-link model elements different from each other on the three-dimensional space model.
