To provide a flying object detector, a flying object detection method and a flying object detection system for appropriately reducing erroneous detection of a flying object in accordance with the environment of a monitoring area and suppressing the degradation of flying object recognition accuracy.SOLUTION: A monitoring device 10 as a flying object detector comprises: a communication unit 31 for communicating with a first camera with its optical axis direction adjustable and arranged so as to be capable of imaging a monitoring area or a microphone array arranged so as to be capable of collecting sounds of the monitoring area; and a signal processing unit 33 which, when the noise level included in the collected sounds of the monitoring area exceeds a prescribed value, suppresses a sound parameter that indicates the magnitude of a sound by a prescribed value, and detects the presence of an unmanned flying object in the monitoring area on the basis of the sound parameter that indicates the magnitude of a collected sound or the suppressed sound parameter.SELECTED DRAWING: Figure 6

    【課題】モニタリングエリアの環境に応じて無人飛行体の誤検知を的確に低減し、無人飛行体の認識精度の劣化を抑制する飛行物体検知装置、飛行物体検知方法および飛行物体検知システムを提供する。【解決手段】飛行物体検知装置としての監視装置10は、光軸方向を調整可能であってモニタリングエリアを撮像可能に配置された第1カメラ、またはモニタリングエリアの音を収音可能に配置されたマイクアレイとの間で通信する通信部31と、収音されたモニタリングエリアの音に含まれる騒音レベルが既定値以上となる場合、音の大きさを示す音パラメータを所定値ほど抑圧処理し、収音された音の大きさを示す音パラメータまたは抑圧処理された音パラメータに基づいて、モニタリングエリアでの無人飛行体の有無を検知するプロセッサとしての信号処理部33と、を備える。【選択図】図6
