Zusammenfassung: | The present invention relates to a hydrophone (two-band hydrophone), simultaneously receiving a target signal in other specific frequency ranges in addition to a signal reflected from a target (underwater target). According to embodiments of the present invention, the hydrophone can comprise: a piezoelectric body stacked with a plurality of piezoelectric elements and a plurality of electrode plates; a front surface weight fastened to one surface of the piezoelectric body; an insulation layer formed on the other surface of the piezoelectric body; an elastic body formed on the insulation layer; a rear surface weight fastened to the elastic body; and a fixing unit fixing the rear surface weight.
본 발명은, 표적(수중 표적)으로부터 반사되는 신호 이외에 다른 특정 주파수 대역에서의 표적 신호를 동시에 수신하는 하나의 하이드로폰(2대역 하이드로폰)에 관한 것으로서, 본 명세서의 실시예들에 따른 하이드로폰은, 복수의 압전소자와 복수의 전극판으로 적층된 압전체와; 상기 압전체의 일면에 체결된 전면추와; 상기 압전체의 타면에 형성된 절연층과; 그 절연층에 형성된 탄성체와; 상기 탄성체에 체결된 후면추와; 상기 후면추를 고정시키는 고정부를 포함할 수 있다. |
