  • Interface Design for Sonobuoy Systems
    Interface Design for Sonobuoy Systems by Huei-Yen Winnie Chen A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Applied Science in Systems Design Engineering Waterloo, Ontario, Canada, 2007 ©Huei-Yen Winnie Chen 2007 AUTHOR'S DECLARATION I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Modern sonar systems have greatly improved their sensor technology and processing techniques, but little effort has been put into display design for sonar data. The enormous amount of acoustic data presented by the traditional frequency versus time display can be overwhelming for a sonar operator to monitor and analyze. The recent emphasis placed on networked underwater warfare also requires the operator to create and maintain awareness of the overall tactical picture in order to improve overall effectiveness in communication and sharing of critical data. In addition to regular sonar tasks, sonobuoy system operators must manage the deployment of sonobuoys and ensure proper functioning of deployed sonobuoys. This thesis examines an application of the Ecological Interface Design framework in the interface design of a sonobuoy system on board a maritime patrol aircraft. Background research for this thesis includes a literature review, interviews with subject matter experts, and an analysis of the decision making process of sonar operators from an information processing perspective. A work domain analysis was carried out, which yielded a dual domain model: the domain of sonobuoy management and the domain of tactical situation awareness address the two different aspects of the operator's work.

We also examined the revised histories issued by the US Coast Guard Historical Center and the US Naval Historical Center, both of which claimed The U-869 the sinking was a result of a depth charge attack by two US Navy vessels in 1945. The conclusion we reached was that the attack by the destroyers was most likely Reexamined, Part on the already-wrecked U-869. If our conclusion is correct, then how did the U-869 come to be on the III bottom of the Atlantic? The Loss of the German Submarine Early Theories The most effective and successful branch of the German By John Chatterton, Richie Kohler, and John Yurga Navy in World War II was the U-boat arm. Hitler feared he would lose in a direct confrontation with the Royal Navy, so the German surface fleet largely sat idle at anchor. Meanwhile, the U-boats and their all- volunteer crews were out at sea, hunting down enemy vessels. They sank the merchant vessels delivering the Allies’ much-needed materials of war, and even were able to achieve some success against much larger enemy warships.

  • Maritime Patrol Aviation: 90 Years of Continuing Innovation
    J. F. KEANE AND C. A. EASTERLING Maritime Patrol Aviation: 90 Years of Continuing Innovation John F. Keane and CAPT C. Alan Easterling, USN Since its beginnings in 1912, maritime patrol aviation has recognized the importance of long-range, persistent, and armed intelligence, surveillance, and reconnaissance in sup- port of operations afl oat and ashore. Throughout its history, it has demonstrated the fl ex- ibility to respond to changing threats, environments, and missions. The need for increased range and payload to counter submarine and surface threats would dictate aircraft opera- tional requirements as early as 1917. As maritime patrol transitioned from fl ying boats to land-based aircraft, both its mission set and areas of operation expanded, requiring further developments to accommodate advanced sensor and weapons systems. Tomorrow’s squad- rons will possess capabilities far beyond the imaginations of the early pioneers, but the mis- sion will remain essentially the same—to quench the battle force commander’s increasing demand for over-the-horizon situational awareness. INTRODUCTION In 1942, Rear Admiral J. S. McCain, as Com- plane. With their normal and advance bases strategically mander, Aircraft Scouting Forces, U.S. Fleet, stated the located, surprise contacts between major forces can hardly following: occur. In addition to receiving contact reports on enemy forces in these vital areas the patrol planes, due to their great Information is without doubt the most important service endurance, can shadow and track these forces, keeping the required by a fl eet commander.

  • Displaying Bioacoustic Directional Information from Sonobuoys Using “Azigrams”

This information enables computation of azimuths of low-frequency acous- tic sources from a single compact sensor. The standard approach for estimating azimuth from these sensors is by conventional beamforming (i.e., adding weighted time series), but the resulting “cardioid” beampattern is imprecise, computationally expensive, and vulnerable to directional noise contamination for weak signals. Demonstrated here is an alternative multiplicative processing scheme that computes the “active intensity” of an acoustic signal to obtain the dominant direction- ality of a noise field as a function of time and frequency. This information is conveniently displayed as an “azigram,” which is analogous to a spectrogram, but uses color to indicate azimuth instead of intensity.

  • Underwater Mines - Past, Present and Future
    UNDERWATER MINES - PAST, PRESENT AND FUTURE Prof. S.Veerabhadraiah1, Dr. M.Purnachandra Rao2 1Department of Electronics and Communication Engineering, Raghu Engineering College, Visakhapatnam, Andhra Pradesh, (India) 2Professor of Physics, Head, Department of Systems Design, Andhra University, Visakhapatnam, Andhra Pradesh, (India) ABSTRACT Some examples of past, present and future mines available in the world are initially covered in this paper. This paper makes an assessment of present day underwater Mines technology for various applications in the area of defensive as well as offensive mining. The capabilities of underwater mines namely, operating as automatic sentinels in deep waters and easy deployment for offensive applications as well, meeting the future needs of naval task forces have also been covered in this paper. Finally the limitations of past and present mines are identified and the solutions to overcome these limitations so as to develop a state of the art mine are suggested towards the end of this paper. Keywords: Automatic Sentinels, Contact Mines, Influence Mines, Underwater Mine, World War I. I. INTRODUCTION A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, an enemy vessel. Naval mines can be used offensively—to hamper enemy shipping movements or lock vessels into a harbour; or defensively—to protect friendly vessels and create "safe" zones. The Sea Mine which was earlier thought to be a poor nation‘s weapon has attained a position of prime importance in the armories of many navies of the world.

  • Bistatic Sonobuoy Deployment Strategies for Detecting Stationary and Mobile Underwater Targets
    Bistatic Sonobuoy Deployment Strategies for Detecting Stationary and Mobile Underwater Targets Mumtaz Karatas Emily Craparo (1) Industrial Engineering Department Department of Operations Research Naval Academy, National Defense University Naval Postgraduate School Istanbul, 34940, TURKEY Monterey, CA 93943, USA [email protected] [email protected] (2) Bahcesehir University Istanbul, 34353, TURKEY Gülşen Akman Industrial Engineering Department Kocaeli University Kocaeli, 41380, TURKEY [email protected] ABSTRACT The problem of determining effective allocation schemes of underwater sensors for surveillance, search, detection, and tracking purposes is a fundamental research area in military OR. Among the various sensor types, multistatic sonobuoy systems are a promising development in submerged target detection systems. These systems consist of sources (active sensors) and receivers (passive sensors), which need not be collocated. A multistatic sonobuoy system consisting of a single source and receiver is called a bistatic system. The sensing zone of this fundamental system is defined by Cassini ovals. The unique properties and unusual geometrical profile of these ovals distinguish the bistatic sensor allocation problem from conventional sonar placement problems. This study is aimed at supporting decision makers in making the best use of bistatic sonobuoys to detect stationary and mobile targets transiting through an area of interest. We use integral geometry and geometric probability concepts to derive analytic expressions for the optimal source and receiver separation distances to maximize the detection probability of a submerged target. We corroborate our analytic results using Monte Carlo simulation. Our approach constitutes a valuable “back of the envelope” method for the important and difficult problem of analyzing bistatic sonar performance.

Measuring currents is a fundamental practice of physical oceanographers. A year baseline inventory of modeling techniques was updated with the latest developments, including basic mathematics and references to the key literature, to guide soundscape practitioners to the most efficient modeling techniques for any given application. The bottom structure is modeled as a fluid sediment layer over a solid half-space. He has conducted more than 60 scientific expeditions in the Arctic, Atlantic, Pacific, and Indian Oceans. Ocean acidification, which occurs when CO 2 in the atmosphere reacts with water to create carbonic acid H 2 CO 3 , has increased. Most traditional active sonars are configured in what is termed a monostatic geometry, meaning that the source and receiver are at the same position.
