HYDROPHONE FOR AN UNDERWATER ANTENNA

A hydrophone for an underwater antenna is disclosed, comprising two hemispherical shells (11, 12) that are combined into a hollow sphere (10) and are made of radially polarized, piezoelectric material, and electrodes (111, 112, 121, 122) which cover the internal and external shell surfaces. The annu...

Zusammenfassung:	A hydrophone for an underwater antenna is disclosed, comprising two hemispherical shells (11, 12) that are combined into a hollow sphere (10) and are made of radially polarized, piezoelectric material, and electrodes (111, 112, 121, 122) which cover the internal and external shell surfaces. The annular edges of the hemispherical shells (11, 12) are mirror-symmetrically placed on the bottom surface and top surface of a support plate (13) which is made of electrically insulating material and on which the hemispherical shells (11, 12) are mounted. The support plate (13) has contact surfaces (173-176) which are connected to integrated strip conductors and with which the electrodes (111, 112, 121, 122) are contacted.
