AIRCRAFT-ANTENNA CONTROLLING DEVICE, AIRCRAFT, AIRCRAFT-ANTENNA SELECTING PROGRAM, AND AIRCRAFT-ANTENNA CONTROLLING METHOD

摘要

A control unit of an aircraft includes a computer that predicts the current position of a wingman aircraft based on a temporal change in wingman-aircraft position information indicating the position of the wingman aircraft; an antenna selector that selects, from among multiple antennas, an antenna with which the elongation φt with respect to the center axis of the antenna at the predicted current position of the wingman aircraft predicted by the computer falls within a coverage angle θ; and a beam controller that executes communication with the wingman aircraft via the antenna selected by the antenna selector. Thus, the control unit of the aircraft can select an optimal antenna for communication with the wingman aircraft from among the multiple antennas.

1. An antenna controlling device for an aircraft having multiple antennas for communicating with a wingman aircraft, the multiple antennas being provided at different points on a fuselage, the aircraft-antenna controlling device comprising:
a wingman-aircraft-position predicting part for predicting the current position of the wingman aircraft based on a temporal change in position information indicating the position of the wingman aircraft; a selecting part for selecting, from among the multiple antennas, an antenna with which the elongation with respect to the center axis of the antenna at the current position of the wingman aircraft predicted by the wingman-aircraft-position predicting part falls within a coverage angle; and a communication controlling part for executing communication with the wingman aircraft via the antenna selected by the selecting part, wherein, in the case where multiple antennas have been selected by the selecting part, one of the selected multiple antennas is selected based on the difference between the coverage angle and the elongation of each of the antennas.
