Abstract: A flying object detection system includes a sensor including a microphone array configured to collect a sound in a first detection area of a monitoring area, a radar configured to measure a distance to a flying object by detecting the flying object in flight in a second detection area of the monitoring area, and a control device configured to detect presence or absence of the flying object based on sound data on the sound in the first detection area collected by the microphone array, and configured to receive the distance to the flying object. The control device is configured to display information on a position of the flying object viewed from arrangement places of the sensor and the radar based on the distance to the flying object and a detection output of the flying object by the radar on a first monitor.
