Claims (12)
- コア(16)を取り囲むように配置された壁(14)を有するシェル(12)を含み、前記シェルが、反射器から反射音響信号出力(22)をもたらすように集束され音波(18)の入射の面域(20)に対向して配置されたシェルの面域から反射されるシェルに入射する音波を、コアの中に伝達することができる音響反射器(10)であって、
コア(16)は、球または真直ぐな円柱の形であり、840ms−1から1500ms−1までの圧縮波速度を有する固体材料の1つまたは複数の同心層から形成され、シェル(12)は、シェルに入射する音波(18)の一部がシェル壁の中に結合されシェルの外周の内部および周りに案内され、次いで強化された反射音響信号出力(22)をもたらすように再放射されて、前記反射音響信号出力と強めあうように結合するようにコアに対して寸法決めされることを特徴とする、音響反射器(10)。 - コア(16)が、850ms−1と1300ms−1との間の圧縮波速度を有する単一の固体材料から形成される、請求項1に記載の音響反射器。
- コア(16)がエラストマー材料から形成される、請求項1または2に記載の音響反射器。
- エラストマー材料がシリコーンである、請求項3に記載の音響反射器。
- シェル(12)が剛性材料から形成される、請求項1から4のいずれかに記載の音響反射器。
- 剛性材料がガラス強化プラスチック(GRP)材料である、請求項5に記載の音響反射器。
- 剛性材料が鋼である、請求項5に記載の音響反射器。
- 剛性材料がガラス入りナイロンである、請求項6に記載の音響反射器。
- コア(16)が、コアの中に伝達される音波の集束を強化するように構成された1つまたは複数の更なる材料を含む、請求項2から8のいずれかに記載の音響反射器。
- 強化された反射音響信号出力(22)が、同一の音波について他の反射器から識別を行うのに十分に特徴的である、請求項1から9のいずれかに記載の音響反射器。
- 信号出力がそのスペクトル内容によって特徴づけられる、請求項9に記載の音響反射器。
- 囲壁を画定するシェル部材(12)および前記囲壁を占有するコア部材(16)を含み、前記シェル部材が、反射器から反射音響信号出力(22)をもたらすように集束され音波(18)の入射の面域(20)に対向して配置されたシェルの面域から反射されるシェル部材に入射する音波を、コアの中に伝達するように構成された音響反射器(10)であって、
コア(16)は、球または真直ぐな円柱の形であり、840ms−1から1500ms−1までの圧縮波速度を有する固体材料の1つまたは複数の同心層から形成され、シェル部材(12)は、シェル部材に入射する音波(18)の一部がシェル部材の中に結合され、シェル部材の外周の周りを通過し、そして強化された反射音響信号出力(22)をもたらすように再放射されて、前記反射音響信号出力と強めあうように結合するようにコアに対して寸法決めされることを特徴とする、音響反射器(10)。
