Claims (2)
- 監視水域の水中に設置され船舶の通航によって生じる水中の物理的状態の変化を検知するセンサと、当該センサからの信号を処理し、処理の結果得られた信号様態によって船舶通航の認知を行うための信号処理装置を具備して成る船舶通航監視装置において、前記センサは磁界および磁界変化を検出するとともに、前記信号処理装置は少なくとも前記検出された磁界変化に含まれる、通航船舶が有する回転機構に起因して生ずる磁界変化に基づいて通航船舶の類識別を行う手段を備えていることを特徴とする船舶通航監視装置。
- 信号処理装置として、前記磁気センサの信号を0.1Hz以下の直流成分とそれ以外の交流成分に分ける過程と直流成分の波形分析を行う過程と交流成分の周波数分析を行う過程を経て船舶の認知及び通航船舶の類識別を行うプログラムを備えることを特徴とする請求項1に記載の船舶通航監視装置。
