Available in PDF, EPUB and Kindle. Book excerpt: In RF communications with a rotorcraft such as a helicopter, the rotor blades can impart a modulation onto the received signal called Rotor Blade Modulation (RBM). This modulation is caused by the reflection of a signal off the rotating blades. The reflected signal is Doppler shifted based on where the signal is reflected along the length of the blade as well as the angle between the axis of rotation and the emitter. RBM is known to degrade the performance of RF communications on rotorcraft and can be used in radar applications to detect and classify aircraft, but there is little on its usefulness in other areas. This thesis looks at the ability to utilize the RBM phenomenon on the rotorcraft itself to geo-locate and track a signal emitter on the ground. To do this a 3D RF ray tracing program was developed in C++ to produce simulations of RBM signals. The developed program is based on optical ray tracing algorithms with modified physical propagation effects for RF signals, and swapping lights and cameras for RF transmitters and receivers respectively. The ray tracer was then run over a realistic set of physical parameters to determine their effects on the received signal; this includes transmitter azimuth and elevation angle, receiver position, blade pitch, etc. along with their combinations. The simulations of the azimuth and elevation angle produce predictable modulations on the received signal. Based on the trends in the signal\'s modulation, a DSP algorithm was distilled down that accurately determines the azimuth and elevation angle of the transmitter from simulated signal data.

This book was released on 2012-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rarely is a reader exposed to such an extraordinary, multifaceted presentation of aerospace technology as Bob Brulle narrates in this book. After returning from duty as a combat fighter pilot in World War II, this Belgian immigrant developed a multitalented and innovative aerospace career path that addressed many of the aerospace professions. Along the way he forged a career in the aviation and space field that resulted in his participating in several of the most momentous aerospace achievements of the past century. He also expanded his education through hard work to a level at which he was qualified to teach graduate-level aerospace engineering courses. It is interesting to follow how the analysis and design techniques of aerospace vehicles progressed over the years, which incidentally reveals the large role that the computer played in making that possible. The story on the early Cape Canaveral operations was amusing and showed that enterprising innovations played a large role in a successful undertaking. Some of the projects described were a surprise, as I had never heard of them, like reading how a pencil-shaped missile was built that could fly and maneuver over an intercontinental distance at a high hypersonic velocity. He also described how American engineers and scientists fought the Cold War battle for technological supremacy on their desks and in their laboratories. The initiatives by which this enterprising engineer develops his technical approach to a project are very informative and offer the reader an insight into the workings of successful operations. He achieves an interesting behind-the-scenes look at how aerospace history is made by weaving in the historical significance of these projects as they are developed. As a former aeronautical engineer at the rapidly growing Mc- Donnell Aircraft Corporation, Bob gives us an interesting exposure to the importance of top management's relationship with the workforce in a successful company. "Mr. Mac" made it a point to make all his employees team members by frequent communication and friendly association.
Download or read book The Russian Way of War written by Lester W. Grau and published by Mentor Military. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Force Structure, Tactics, and Modernization of the Russian Ground Forces The mighty Soviet Army is no more. The feckless Russian Army that stumbled into Chechnya is no more. Today's Russian Army is modern, better manned, better equipped and designed for maneuver combat under nuclear-threatened conditions. This is your source for the tactics, equipment, force structure and theoretical underpinnings of a major Eurasian power. Here's what the experts are saying: "A superb baseline study for understanding how and why the modern Russian Army functions as it does. Essential for specialist and generalist alike." -Colonel (Ret) David M. Glantz, foremost Western author on the Soviet Union in World War II and Editor of The Journal of Slavic Military Studies. "Congratulations to Les Grau and Chuck Bartles on filling a gap which has yawned steadily wider since the end of the USSR. Their book addresses evolving Russian views on war, including the blurring of its nature and levels, and the consequent Russian approaches to the Ground Forces' force structuring, manning, equipping, and tactics. Confidence is conferred on the validity of their arguments and conclusions by copious footnoting, mostly from an impressive array of primary sources. It is this firm grounding in Russian military writings, coupled with the authors' understanding of war and the Russian way of thinking about it, that imparts such an authoritative tone to this impressive work." -Charles Dick, former Director of the Combat Studies Research Centre, Senior Fellow at the Defence Academy of the United Kingdom, author of the 1991 British Army Field Manual, Volume 2, A Treatise on Soviet Operational Art and author of From Victory to Stalemate The Western Front, Summer 1944 and From Defeat to Victory, The Eastern Front, Summer 1944. "Dr. Lester Grau's and Chuck Bartles' professional research on the Russian Armed Forces is widely read throughout the world and especially in Russia. Russia's Armed Forces have changed much since the large-scale reforms of 2008, which brought the Russian Army to the level of the world's other leading armies. The speed of reform combined with limited information about their core mechanisms represented a difficult challenge to the authors. They have done a great job and created a book which could be called an encyclopedia of the modern armed forces of Russia. They used their wisdom and talents to explore vital elements of the Russian military machine: the system of recruitment and training, structure of units of different levels, methods and tactics in defense and offence and even such little-known fields as the Arctic forces and the latest Russian combat robotics." -Dr. Vadim Kozyulin, Professor of Military Science and Project Director, Project on Asian Security, Emerging Technologies and Global Security Project PIR Center, Moscow. "Probably the best book on the Russian Armed Forces published in North America during the past ten years. A must read for all analysts and professionals following Russian affairs. A reliable account of the strong and weak aspects of the Russian Army. Provides the first look on what the Russian Ministry of Defense learned from best Western practices and then applied them on Russian soil." -Ruslan Pukhov, Director of the Moscow-based Centre for the Analysis of Strategies and Technologies (CAST) and member of the Public Council of the Russian Federation Ministry of Defense. Author of Brothers Armed: Military Aspects of the Crisis in Ukraine, Russia's New Army, and The Tanks of August.

Book excerpt: A broadly accessible introduction to robotics that spans the most basic concepts and the most novel applications; for students, teachers, and hobbyists. The Robotics Primer offers a broadly accessible introduction to robotics for students at pre-university and university levels, robot hobbyists, and anyone interested in this burgeoning field. The text takes the reader from the most basic concepts (including perception and movement) to the most novel and sophisticated applications and topics (humanoids, shape-shifting robots, space robotics), with an emphasis on what it takes to create autonomous intelligent robot behavior. The core concepts of robotics are carried through from fundamental definitions to more complex explanations, all presented in an engaging, conversational style that will appeal to readers of different backgrounds. The Robotics Primer covers such topics as the definition of robotics, the history of robotics (“Where do Robots Come From?”), robot components, locomotion, manipulation, sensors, control, control architectures, representation, behavior (“Making Your Robot Behave”), navigation, group robotics, learning, and the future of robotics (and its ethical implications). To encourage further engagement, experimentation, and course and lesson design, The Robotics Primer is accompanied by a free robot programming exercise workbook that implements many of the ideas on the book on iRobot platforms. The Robotics Primer is unique as a principled, pedagogical treatment of the topic that is accessible to a broad audience; the only prerequisites are curiosity and attention. It can be used effectively in an educational setting or more informally for self-instruction. The Robotics Primer is a springboard for readers of all backgrounds—including students taking robotics as an elective outside the major, graduate students preparing to specialize in robotics, and K-12 teachers who bring robotics into their classrooms.
Download or read book Handbook of Modern Sensors written by Jacob Fraden and published by Springer Science & Business Media. This book was released on 2006-04-29 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the sel- tivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying. He was saying, “Oh Lord, thanks for Thou do not violate your own laws. ” It is comforting indeed that the laws of Nature do not change as time goes by; it is just our appreciation of them that is being re?ned. Thus, this new edition examines the same good old laws of Nature that are employed in the designs of various sensors. This has not changed much since the previous edition. Yet, the sections that describe the practical designs are revised substantially. Recent ideas and developments have been added, and less important and nonessential designs were dropped. Probably the most dramatic recent progress in the sensor technologies relates to wide use of MEMS and MEOMS (micro-electro-mechanical systems and micro-electro-opto-mechanical systems). These are examined in this new edition with greater detail. This book is about devices commonly called sensors. The invention of a - croprocessor has brought highly sophisticated instruments into our everyday lives.
