Aiming at problem of target detecting under water

a hydrophone with low frequency

small size

high sensitivity and strong anti-interference capability is put forward.The presented integrated scalar hydrophone solves the contradiction between the size and frequency response through choosing the best balance point and increasing gain in the circuit parts

meanwhile aimed at how to reduce the hydrophone interference issues

high input impedance transformation circuit is used in the integrated scalar hydrophone and partial interference is restricted

using absorption structure with damp

electrostatic shielding techniques is used and core cable is used to transmit signals to restrain the interference greatly.The result shows the presented integrated scalar hydrophone has low frequency

small size

high sensitivity above-158 dB

and strong anti-interference capability

it can be used for detecting sound signal of target under water.
