Radio communication apparatus, radio wave control method, and storage medium storing radio wave control program

A radio communication apparatus comprising:

• one or more processors;
• and
• one or more memories storing instructions, wherein the one or more processors are configured to execute the instructions to:
• detect an object flying in a vicinity of a propagation path of directional radio waves;
• calculate a distance between the propagation path of the directional radio waves and the detected object;
• determine a first change amount of a transmission power value of the directional radio waves in accordance with the calculated distance, wherein the first change amount is determined as a positive value when the calculated distance is equal to or less than a prescribed distance;
• determine a second change amount of the transmission power value in accordance with a reception power value of a signal when the directional radio waves are received, wherein the second change amount is determined as a positive value when the reception power value is equal to or less than a prescribed threshold value;
• set a control change amount based on the first change amount and the second change amount, wherein the control change amount is set to the second change amount when the calculated distance is equal to or less than the prescribed distance and the reception power value is equal to or less than the prescribed threshold value;
• and
• control the transmission power value that is used to transmit the directional radio waves in accordance with the control change amount that has been set.
