Radar detection system and radar detection method

A radar detection system that detects an obstacle to an aircraft in an airport where a control tower is provided, and where a first aircraft and a second aircraft take off and make a landing, the radar detection system comprising:

• a radar apparatus that is provided in the first aircraft, and is configured to detect an obstacle by transmitting and receiving a radar signal in a three-dimensional range, and acquire obstacle information regarding the obstacle based on the received radar signal, the obstacle information including at least a height of the obstacle;
• a first control apparatus that is provided in the first aircraft, includes an airport coordinate system whose origin is set to a predetermined position in the airport, and is configured to calculate a position of the obstacle in the airport coordinate system based on the obstacle information and the airport coordinate system;
• a first communication apparatus that is provided in the first aircraft, and is configured to transmit the position of the obstacle in the airport coordinate system;
• a second communication apparatus that is provided in the control tower, and is configured to receive the position of the obstacle in the airport coordinate system from the first communication apparatus, and transmit the position of the obstacle in the airport coordinate system;
• a display apparatus that is provided in the control tower, and is configured to display the position of the obstacle in the airport coordinate system;
• a third communication apparatus that is provided in the second aircraft, and is configured to receive the position of the obstacle in the airport coordinate system from the second communication apparatus;
• and
• a second control apparatus that is provided in the second aircraft, and is configured to calculate a possibility that the second aircraft will collide with the obstacle based on a position of the second aircraft in the airport coordinate system, and the position of the obstacle in the airport coordinate system.
