Electronic Warfare Fundamentals
ELECTRONIC WARFARE FUNDAMENTALS NOVEMBER 2000 PREFACE Electronic Warfare Fundamentals is a student supplementary text and reference book that provides the foundation for understanding the basic concepts underlying electronic warfare (EW). This text uses a practical building-block approach to facilitate student comprehension of the essential subject matter associated with the combat applications of EW. Since radar and infrared (IR) weapons systems present the greatest threat to air operations on today's battlefield, this text emphasizes radar and IR theory and countermeasures. Although command and control (C2) systems play a vital role in modern warfare, these systems are not a direct threat to the aircrew and hence are not discussed in this book. This text does address the specific types of radar systems most likely to be associated with a modern integrated air defense system (lADS). To introduce the reader to EW, Electronic Warfare Fundamentals begins with a brief history of radar, an overview of radar capabilities, and a brief introduction to the threat systems associated with a typical lADS. The two subsequent chapters introduce the theory and characteristics of radio frequency (RF) energy as it relates to radar operations. These are followed by radar signal characteristics, radar system components, and radar target discrimination capabilities. The book continues with a discussion of antenna types and scans, target tracking, and missile guidance techniques. The next step in the building-block approach is a detailed description of countermeasures designed to defeat radar systems. The text presents the theory and employment considerations for both noise and deception jamming techniques and their impact on radar systems. -

Below 535 a Historical Review of Continuous Wave Radio Frequency
Below 535 Edited by Frank Lotito, K3DZ 1428 O'Block Rd., Pittsburgh ,PA 15239 Please include SASE for reply A Historical Review of Continuous Wave Radio Frequency Power Generators Overview The many disadvantages of the spark transmitters that were the original means of radio communication eventually led to the development of better methods for generating a radio frequency signal. Herculean-type arc transmitter ably presented in Henry Bradford's recent award winning article on the Marconi transatlantic site in Nova Scotia (1) was one historically significant means of developing large amounts of r.f. power in the long-wave spectrum. This article will briefly review some others. These were the Poulsen Arc transmitter, Alexanderson and Goldschmidt HF generators, and the static frequency changers.1 Hopefully, one or more readers will be enticed to contribute detailed articles on each of these devices. Introduction nbsp; At the start of the twentieth century, wireless communication lost its curiosity status and became a practical means of spanning large distances. "King Spark" ruled the realm. But all too frequently, the spark signals filled the airwaves with a muddle of almost unintelligible overlapping messages! The interference was due to a number of major factors: 1. There was little or no regulation of the airwaves or assignment of priorities. Radio services transmitted whenever they wished and in any part of the radio frequency spectrum they desired. 2. A transmitter "horse power competition" evolved. Those who could afford the more powerful transmitters built them in order to improve their chances of being heard. 3. The very wide bandwidth of the spark transmission2 resulted in lower transmitter efficiency and communications effectiveness, while splattering the r.f. -
1985 1995 the Evolution of Mobile Entertainment
Ask the expert The evolution of mobile entertainment Today’s PC users look at the “fun” side of computing when deciding about their next computer. In fact, today’s notebook users see “mobile entertainment” as a given criteria for any new machine. They expect to be able to play games, listen to music or watch DVD movies on their notebooks. But a mere 20 years ago, “mobile entertainment” as we know it didn’t exist. This feature will look at the major milestones that helped turn today’s mobile computers into “mobile Mobile gaming – The Satellite P30 from 2003 could show 3D games on its entertainers”. The pinnacle of this development can be seen in the Qosmio own highresolution display.

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.

Marine Nuclear Power 1939 – 2018 Part 1 Introduction
Marine Nuclear Power: 1939 – 2018 Part 1: Introduction Peter Lobner July 2018 1 Foreword In 2015, I compiled the first edition of this resource document to support a presentation I made in August 2015 to The Lyncean Group of San Diego (www.lynceans.org) commemorating the 60th anniversary of the world’s first “underway on nuclear power” by USS Nautilus on 17 January 1955. That presentation to the Lyncean Group, “60 years of Marine Nuclear Power: 1955 – 2015,” was my attempt to tell a complex story, starting from the early origins of the US Navy’s interest in marine nuclear propulsion in 1939, resetting the clock on 17 January 1955 with USS Nautilus’ historic first voyage, and then tracing the development and exploitation of marine nuclear power over the next 60 years in a remarkable variety of military and civilian vessels created by eight nations. In July 2018, I finished a complete update of the resource document and changed the title to, “Marine Nuclear Power: 1939 – 2018.” What you have here is Part 1: Introduction. The other parts are: Part 2A: United States - Submarines Part 2B: United States - Surface Ships Part 3A: Russia - Submarines Part 3B: Russia - Surface Ships & Non-propulsion Marine Nuclear Applications Part 4: Europe & Canada Part 5: China, India, Japan and Other Nations Part 6: Arctic Operations 2 Foreword This resource document was compiled from unclassified, open sources in the public domain. I acknowledge the great amount of work done by others who have published material in print or posted information on the internet pertaining to international marine nuclear propulsion programs, naval and civilian nuclear powered vessels, naval weapons systems, and other marine nuclear applications. -

The references are assembled in this form to provide a convenient source of information for use by scientists and engineers who need this kind of specialized compilation. Continuing Bibliographies are updated periodically by supplements which can be appended to the original issue. All references included in SP-7004 (01) have been announced in either Scientific and Technical Aerospace Reports (STAR)or International Aerospace Abstracts (IAA) and were introduced into the NASA information system during the period May, 1964-January, 1965. The transmission of information by means of communications satellites is a new tech- nique that promises to be a powerful stimulus for effective international cooperation in the investigation of space.
