Claim 0:
1. An interference detection system for detecting an interference between feeder links of plural movable aerial-staying type communication 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 system comprising:
an information storage section that stores position information of plural gateway stations for respectively performing a radio communication with the plural communication relay apparatuses;
an information acquisition section that acquires position information on current positions of the plural communication relay apparatuses;
a generation section that generates 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 the position of the communication relay apparatus, a feeder-link transmitting point corresponding to the 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
a determination section that determines 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.
