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

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.

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 ...

The survey of the various augmented spherical wave (ASW) method starts with an outline of the standard scheme. Within the framework of density functional theory and the (semi-)local approximations it allows for both fast and conceptually simple calculations of the ground state properties of solids.

Modelling and experimentation for an unmanned ASW barrier
2023Maritime unmanned systems can be a force multiplier in naval operations. In particular, industrial mine countermeasure (MCM) systems are reaching maturity and navies are transitioning to embrace such systems in the backbone of their capabilities, allowing new concepts of operation. In comparison, unmanned sensor systems for anti submarine warfare (ASW)

ASW Sensors and their Deployment
1986This chapter looks at actual and potential ASW sensors and at ways to deploy them. It will simplify the evaluation of the utility of sensor possibilities if discussion first centres on the relative merits of deployment modes and platforms.

Anti-submarine warfare (ASW) is a multi-step process with its own terminology. After searching for and detecting or acquiring a possible submarine, ASW forces strive to hold the contact and classify it as a false alarm or a true submarine, determining its specific type if possible.

Details of the Standard ASW Method
2012In this and the following chapters details of the various methods are presented, which did not make their way into the early chapters in order not to undermine their readability. In particular, the present chapter elaborates on calculational and numerical aspects of the standard ASW method affecting, e.g., the densities of states and the intraatomic ...
