Ocean 72 - IEEE International Conference on Engineering in the Ocean Environment, 1972
The characteristics of sound transmission, reverberation, and ambient noise under ice differ significantly from those found in the waters of more temperate regions. The environmental factors and their influence upon acoustic behavior in the Arctic and Subarctic are discussed.

IETE Technical Review, 1993
Sound being the only form of energy that can be sustained underwater, sonars play a critical role in ocean surveillance and antisubmarine warfare. This review paper presents various aspects of sonar system design. The propagation of sound in sea water and the oceanic parameters that affect such propagation are presented in brief. Transducers, the front

Evaluation of Asw Tactical Symbology
Proceedings of the Human Factors Society Annual Meeting, 1987Twelve experienced tactical crew members served as subjects in a study which compared three synonymous sets of tactical contact symbols under conditions of color/monochrome and high/low density. Time and accuracy data of responses to stimulus displays were collected and analyzed, and subjective findings were obtained through post-experiment ...

The Soviet Navy or VMF (Voyenno-Morskoy Flot) exhibited no great overt interest in ASW prior to the development of American SSBNs.1 It had no long ocean sea-lanes to protect, and the primary naval concern was to interdict enemy forces approaching the homeland from ocean areas.

Abstract : The objective of this project is to develop a concept design of a Trimaran Small Waterplane Area Centerhull (TriSWACH) Anti Submarine Warfare (ASW) corvette. The advantages of using the TriSWACHs are the hullform s inherent good seakeeping at small displacement, good intact stability, large usable deck area compared to monohulls, and small ...

ASW patrol aircraft of the future
2nd Marine Systems and Antisubmarine Warfare Conference, 1966Certain key considerations in the development of future antisubmarine warfare (ASW) patrol airplanes are discussed. Among these are: the importance of speed; the problem of providing all the features required for the collateral missions traditionally performed by Navy patrol aircraft such as shipping and coastal surveillance, counter-insurgency, and ...

Advanced ASW sonobuoy receivers
Proceedings of TCC'94 - Tactical Communications Conference, 1994Summary form only given, as follows. The development of extremely high sampling rate, high dynamic range A/D converters has resulted in the feasibility of a mostly digital telemetry receiver. The Naval Command and Control and Ocean Surveillance Center, under Office of Navy Research funding is developing an advanced ASW receiver which implements RF ...

ASW Not Just a Navy Sport. The need for Joint ASW
2006Abstract : ASW is an asset-intensive team sport that requires the efforts of the Navy's air, surface and subsurface communities. Today's ASW threat is different and more challenging than during the Cold War. A confluence of post-Cold War events vastly changed the nature of ASW and the way it needs to be approached in the future.

1986
Anti-submarine warfare (ASW) has had a high priority in the United States since the Second World War. The onset of the Cold War and the USSR's ambitious post-war submarine building programme – which gave it about 450–550 submarines in the mid-1950s – reinforced Western fears of another Battle of the Atlantic.

ASW helicopter mission avionics
IEEE Aerospace and Electronic Systems Magazine, 1988The requirements and subsequent mechanization of the mission avionics of the US Navy's new fleet antisubmarine warfare helicopter, the SH-60F CV Inner Zone ASW Weapon System (CV HELO) are discussed. The overall system architecture is described, and its major functional elements are examined.
