ABSTRACT:
An active, low-profile hydrophone for use in aquatic environments having substantially turbulent flow conditions. The hydrophone is generally pisciform such that it may lie substantially flat on the water bottom and oriented in the current so as to reduce ambient noise associated with the turbulent flow. The enclosed sensors are oriented such that they are insensitive to acceleration and are coupled to a unity gain amplifier network also contained within the hydrophone.
