The United States Navy's Atlantic Undersea Test and Evaluation Center (AUTEC) is a laboratory that performs integrated three-dimensional hydrospace/aerospace trajectory measurements covering the entire spectrum of undersea simulated warfare – calibration, classifications, detection, and destruction.
For these reasons, active sonar is not frequently used by military submarines. A very directional, but low-efficiency, type of sonar (used by fisheries, military, and for port security) makes use of a complex nonlinear feature of water known as non-linear sonar, the virtual transducer being known as a parametric array.
The sonar modified for the test was an early version of SURTASS deployed in the MV Cory Chouest. [10] As a result of this test a "Committee on Low-Frequency Sound and Marine Mammals" was organized by the National Research Council. Their findings were published in 1994, in Low-Frequency Sound and Marine Mammals: Current Knowledge and Research Needs.
Postcard aerial view of Goat Island. The Naval Undersea Warfare Center (NUWC) is the United States Navy's full-spectrum research, development, test and evaluation, engineering and fleet support center for submarines, autonomous underwater systems, and offensive and defensive weapons systems associated with undersea warfare.
The Canadian Forces Maritime Experimental and Test Ranges (CFMETR) is a maritime test facility on the east [1] side of Vancouver Island, at Nanoose Bay. The main gate of CFMETR Nanoose Bay CFMETR docks from across Nanoose Bay. The craft shown, from left to right, are two Canadian Maritime Command TSRVs and one U.S. Navy YTT.
Project Artemis was a United States Navy acoustics research and development experiment from the late 1950s into the mid 1960s to test a potential low-frequency active sonar system for ocean surveillance. The at sea testing began in 1960 after research and development in the late 1950s.
The source is a vertical line array (VLA) of up to 18 source projectors suspended below the vessel. LFA’s transmitted sonar beam is omnidirectional (i.e., a full 360 degrees) in the horizontal (nominal depth of the LFA array center is 120 m [400 ft]), with a narrow vertical beamwidth that can be steered above or below the horizontal.
