WIRELESS COMMUNICATION DEVICE, WIRELESS WAVE CONTROL METHOD, AND WIRELESS WAVE CONTROL PROGRAM

To provide a wireless communication device, a wireless wave control method, and a wireless wave control program that can prevent the deterioration of wireless wave communication quality even when a flying object invades a wireless wave propagation path.SOLUTION: A wireless communication device 10 according to an embodiment of the present invention includes a detection unit 101 that detects an object that has flown in the vicinity of a directional wireless wave propagation path, a distance calculation unit 102 that calculates a distance between the wireless wave propagation path and an object detected by the detection unit 101, a change amount determination unit 103 that determines the change amount of a transmission power value which is a power value used for transmitting wireless waves according to the distance calculated by the distance calculation unit 102, and a signal control unit 104 that controls a transmission power value on the basis of the change amount determined by the change amount determination unit 103. When the calculated distance is equal to or less than a predetermined distance, the change amount determination unit 103 sets the change amount as a positive value.SELECTED DRAWING: Figure 3 【課題】飛来した物体が電波の伝搬路に侵入した場合でも、電波通信品質が低下するのを防止可能な無線通信装置、電波制御方法及び電波制御プログラムを提供すること。【解決手段】本発明の例示的な一態様に係る無線通信装置１０は、指向性を有する電波の伝搬路の近傍に飛来した物体を検出する検出部１０１と、電波の伝搬路と検出部１０１が検出した物体との距離を算出する距離算出部１０２と、距離算出部１０２が算出した距離に応じて、電波の送信に使用される電力値である送信電力値の変化量を決定する変化量決定部１０３と、変化量決定部１０３が決定した変化量に基づいて、送信電力値を制御する信号制御部１０４とを含む。変化量決定部１０３は、算出した距離が既定の距離以下である場合、変化量を正の値とする。【選択図】図３
