To provide a tracking antenna system capable of stably transmitting a large capacity of data between a missile and a ground station in a configuration in which the ground station transmits and receives a radio signal to/from the missile while tracking the radio signal.SOLUTION: In a missile 200, the missile autonomously selects n antennas from m mounted antennas on the basis of on-board information, such as position, speed, attitude, and predicted orbit and position information of a ground station 100, and transmits/receives, transmits, or receives data. If a position relation between the missile and the ground station changes due to flight after the lapse of a fixed time even though the missile 200 performs transmission from two antennas 220.2 and 220.3 in Fig., the missile autonomously selects a plurality of antennas that can stably transmit a large capacity of data, that is, antennas for transmitting a radio signal from the on-board information. Further, the ground station causes the antennas to track the direction of the missile so that a large capacity of data can stably be transmitted on the basis of position information from the missile.SELECTED DRAWING: Figure 1
【課題】飛翔体からの無線信号を地上局で追尾しながら送受信する構成において、飛翔体と地上局間で大容量のデータを安定的に伝送可能な追尾アンテナシステムを提供する。【解決手段】飛翔体200において、位置、速度、姿勢、予測軌道、送受信パターンなどの機上情報と地上局100の位置情報に基づいて、飛翔体が自律的にm個の搭載アンテナからn個のアンテナを選択し、データの送受信または送信または受信を行う。図では、飛翔体200は、2つのアンテナ220.2と220.3により送信しているが、一定時間経過後、飛行により飛翔体と地上局との位置関係が変化した場合、飛翔体は、無線信号を送信するアンテナを機上情報から、大容量のデータを安定的に伝送できる複数のアンテナを自律的に選択する。さらに、地上局は、飛翔体からの位置情報に基づいて、大容量のデータを安定的に伝送できるように、アンテナを飛翔体の方向に追尾させる。【選択図】図1
