Book Propagation Through a Random Medium and Its Effects on Antennas that Maximize Information Transfer

Download or read book Propagation Through a Random Medium and Its Effects on Antennas that Maximize Information Transfer written by Charles J. Drane (Jr.) and published by . This book was released on 1969 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical communication theory has been applied to the problem of the analysis and optimization of controlled systems that process electromagnetic fields of an information-carrying nature. Maximum information transfer is the objective, which is achieved by a maximization of the transcorrelation function (a space-time average of the correlation between input and output signals of the communications system) relative to various parameters of the system. These techniques have been used in the optimization of the amplitude and phase taper of a receiving array that is part of a communications link in which a fluctuating medium intervenes between transmitter and receiver. The relationship between the transcorrelation function and these antenna parameters has been established. It is the specific purpose of this paper to establish in turn the relationship between the transcorrelation function and the statistical properties of the constitutive parameters of the medium that generally lead to a decorrelation of the transmitted signal.

Book Study of Application of Antenna Optimization Techniques

Download or read book Study of Application of Antenna Optimization Techniques written by G. O. Young and published by . This book was released on 1967 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research dealt with decision theoretic antenna processing systems and the development and application of a new coherence theory to optimum antenna system design. The objective was the development of techniques that would result in improved target parameter estimates and better detection and resolution capability than those achieved by conventional systems. A new theory was developed, called transcoherence theory. It can be used to determine the optimum amplitude and/or phase shading for an antenna that is intended as an information-gathering device. It is particularly useful when employed for the purpose of compensating for deleterious medium effects. The theory can also be used to find the coherence properties of sources, where these properties are essential to the specification of the a priori statistics of target signals and clutter. A relatively simple decision theoretic processor was built and found to improve angular resolution by at least a factor of four over that of conventional systems. The research studies and their results are documented in seven scientific reports and several papers. (Author).

Book Angular Resolution Beyond the Rayleigh Limit

Download or read book Angular Resolution Beyond the Rayleigh Limit written by Aharon A. Ksienski and published by . This book was released on 1966 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of angular resolution is formulated in a statistical decision theoretic context. A tutorial discussion of decision theory and its application to resolution is presented, and an explicit signal processing radar system is derived whose resolving properties approach an optimum. Computer simulation tests show that the system is capable of reliably resolving targets as close as a quarter of a 3-db beamwidth in the presence of noise and system errors. (Author).

Book The Star Gate Archives

Download or read book The Star Gate Archives written by Edwin C. May and published by McFarland. This book was released on 2018-11-02 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: Star Gate is the largest funded program in the history of psi research receiving about $19.933 million in funding from 1972 to 1995. Researchers from SRI International, and later at Science Applications International Corporation, in association with various U.S. intelligence agencies participated in this program. Using the remote viewing method, research focused on understanding the applicability and nature of psi in general but mostly upon informational psi. Volume 1: Remote Viewing (1972-1984) and Volume 2: Remote Viewing (1985-1995) include all aspects of RV including laboratory trials and several operational results. Volume 3 focuses on laboratory investigations on psychokinesis. Volume 4: Operational Remote Viewing: Government Memorandums and Reports includes an analysis of the applied remote viewing program and a selection of documents that provide a narrative on the behind the scenes activities of Star Gate. In a total of 504 separate missions from 1972 to 1995, remote viewing produced actionable intelligence prompting 89% of the customers to return with additional missions. The Star Gate data indicate that informational psi is a scientifically valid phenomenon. These data have led to the development of a physics and neuroscience based testable model for the underlying mechanism, which considers informational psi as a normal, albeit atypical, phenomenon. The Star Gate data found insufficient evidence to support the causal psi (psychokinesis) hypothesis.

Book The Cellular Automaton Interpretation of Quantum Mechanics

Download or read book The Cellular Automaton Interpretation of Quantum Mechanics written by Gerard 't Hooft and published by Springer. This book was released on 2016-09-02 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the deterministic view of quantum mechanics developed by Nobel Laureate Gerard 't Hooft. Dissatisfied with the uncomfortable gaps in the way conventional quantum mechanics meshes with the classical world, 't Hooft has revived the old hidden variable ideas, but now in a much more systematic way than usual. In this, quantum mechanics is viewed as a tool rather than a theory. The author gives examples of models that are classical in essence, but can be analysed by the use of quantum techniques, and argues that even the Standard Model, together with gravitational interactions, might be viewed as a quantum mechanical approach to analysing a system that could be classical at its core. He shows how this approach, even though it is based on hidden variables, can be plausibly reconciled with Bell's theorem, and how the usual objections voiced against the idea of ‘superdeterminism' can be overcome, at least in principle. This framework elegantly explains - and automatically cures - the problems of the wave function collapse and the measurement problem. Even the existence of an “arrow of time" can perhaps be explained in a more elegant way than usual. As well as reviewing the author’s earlier work in the field, the book also contains many new observations and calculations. It provides stimulating reading for all physicists working on the foundations of quantum theory.

Visual science is the model system for neuroscience, its findings relevant to all other areas. This essential reference to contemporary visual neuroscience covers the extraordinary range of the field today, from molecules and cell assemblies to systems and therapies. It provides a state-of-the art companion to the earlier book The Visual Neurosciences (MIT Press, 2003). This volume covers the dramatic advances made in the last decade, offering new topics, new authors, and new chapters. The New Visual Neurosciences assembles groundbreaking research, written by international authorities. Many of the 112 chapters treat seminal topics not included in the earlier book. These new topics include retinal feature detection; cortical connectomics; new approaches to mid-level vision and spatiotemporal perception; the latest understanding of how multimodal integration contributes to visual perception; new theoretical work on the role of neural oscillations in information processing; and new molecular and genetic techniques for understanding visual system development. An entirely new section covers invertebrate vision, reflecting the importance of this research in understanding fundamental principles of visual processing. Another new section treats translational visual neuroscience, covering recent progress in novel treatment modalities for optic nerve disorders, macular degeneration, and retinal cell replacement. The New Visual Neurosciences is an indispensable reference for students, teachers, researchers, clinicians, and anyone interested in contemporary neuroscience.
