Title
(JA) 媒体内の撹乱を検出して位置特定するためのシステムならびに対応する方法およびコンピュータープログラム
Abstract
(JA)

システムが、媒体(102)内に連続音波を放出するための手段(304、306)、受波される連続音波に基づいて受波信号を供給するように設計された、媒体(102)内のその伝播の後で連続音波を受波するための手段(308)、および受波信号に基づいて媒体内の撹乱を検出して位置特定するための手段を備える。放出手段(304、306)は、各音波の振幅および/または位相スペクトラムが、少なくとも特定の周波数で、振幅または位相の特定の空間分布に従って媒体の中で変動する、振幅または位相を有し、連続音波の振幅または位相のこれらの空間分布が相互に異なるように設計されている。
