Download or read book Modern HF Signal Detection and Direction Finding written by Jay R. Sklar and published by MIT Press. This book was released on 2018-09-25 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed descriptions of detection, direction-finding, and signal-estimation methods, using consistent formalisms and notation, emphasizing HF antenna array sensing applications. Adaptive antenna array technology encompasses many powerful interference suppression approaches that exploit spatial differences among signals reaching a radio receiver system. Today, worldwide propagation phenomenology occurring in the High Frequency (HF) radio regime has made such interference common. In this book, Jay Sklar, a longtime researcher at MIT Lincoln Laboratory, presents detailed descriptions of detection, direction-finding, and signal-estimation methods applicable at HF, using consistent formalisms and notation. Modern electronic system technology has made many of these techniques affordable and practical; the goal of the book is to offer practicing engineers a comprehensive and self-contained reference that will encourage more widespread application of these approaches. The book is based on the author's thirty years of managing MIT Lincoln Laboratory work on the application of adaptive antenna array technologies to the sensing of HF communication signals. After an overview of HF propagation phenomenology, communication signal formats, and HF receiver architectural approaches, Sklar describes the HF propagation environment in more detail; introduces important modulation approaches and signaling protocols used at HF; discusses HF receiver system architectural features; and addresses signal processor architecture and its implementation. He then presents the technical foundation for the book: the vector model for a signal received at an adaptive array antenna. He follows this with discussions of actual signal processing techniques for detection and direction finding, including specific direction-finding algorithms; geolocation techniques; and signal estimation.

Available in PDF, EPUB and Kindle. Book excerpt: Enlarged and revised second edition. Modern direction finders, capable of measuring elevation angles as well as azimuth angles on the components of multi-ray wavefields, have become powerful tools for research in ionospheric physics and HF radio propagation. The complexity of the problem of resolving closely-spaced rays requires the combined use of wide aperture antenna arrays, multichannel receiving systems and sophisticated digital processing techniques.

Download or read book Microwave Passive Direction Finding written by Stephen E. Lipsky and published by SciTech Publishing. This book was released on 2004 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave Passive Direction Finding unifies direction finding (DF) theory and brings together into a single source wide-ranging information on the technology of measuring the direction-of-arrival of microwave signals. Throughout the material, there is authoritative information useful to preparing a detailed technical proposal for new business that has been compiled from many years of defense industry presentations, reports, and systems development. Diagrams and photographs of state-of-the-art equipment depict the methods discussed, and equations and charts facilitate a "hands-on" approach to calculating system performance. The book also presents rarely published systems concepts, such as digital preprocessing, supercommutation, and wide RF bandwidth signal detection methods. Specific sections cover evolution and use of monopulse passive DF receiver theory, design of antenna elements for conformal DF coverage, receiver configurations, DF antenna arrays, interferometer DF techniques, computation methods for signal detection, probability of detection, accuracy of DF systems, and signal processing and display methods. More than any book on this technology, Microwave Passive Direction Finding anticipates the questions that arise in the DF design process. The chapters are organized to stand alone, making the book useful as a text/reference for the practicing engineer. At the same time, the material is organized inductively, so that it can be used for a college or seminar text.

This book was released on 1996 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of spread-spectrum signals has increased dramatically in military radio communications. This report locates methods for direction-finding direct-sequence spread-spectrum (DS/SS) signals; digital methods are of special interest. A literature survey was conducted to see if there are any known methods. Investigated if a DS/SS detection method using a square-law detector can be extended to direction-finding. By use of computer simulations, show the performance of the methods found. Benefits and problems are also discussed.
