Delta Array Sensor Development Deep Ocean Tests.

Abstract

The DELTA System is a deployed, passive, low frequency hydrophone array designed to provide extended ASW detection capability to surface ships without placing restraints on speed or maneuverability. Its detection performance benefits by the inherent low flow-noise of a deployed system which is essentially motionless in the surrounding water. The test array was a linear string of 14 hydrophones, spaced 125 feet apart to permit acoustic data processing with the existing LAMBDA Processing System at Naval Underseas Center, San Diego. Other configurations have been investigated previosly, and the test configuration is not necessarily representative of an optimum operational array.
