This book was released on 2020 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Frequency Diverse Array (FDA) antenna provides range - angle - time dependentbeampattern, potentially generating highly directional beams with high gain that may besteered directly and continuously to the desired position. This research explores using FDAantenna for tracking a Low Earth Orbit (LEO) satellite. Although FDA array antenna hasbeen growing in use for radar communication systems with advantages of it is electronicallybeam steering, it is still not truly used in integrate with LEO systems. The mathematicalmodel of FDA antennas with dierent geometries for tracking LEO satellite is presented.Then, the radiation characteristics of linear and Planar-FDA under dierent situations areinvestigated. Further, the planar FDA array owns greater superiority over the linear FDAarray, and it can cover the observation space indicating great potential in LEO trackingand communication applications. A ground receiving antenna system based on planar FDAarray antenna is presented for tracking and communicating with (LEO) satellite at groundstation. This is required to minimize a complexity and the cost of ground station. Tomeet the system gure of merit (G/T) requirement, the radiation characteristics, the gainrequirements, the array size, the minimum number of elements and their distribution forseveral FDA array antenna architectures are calculated and analyzed. Moreover, a generaloverview of system temperature is presented including a noise model for FDA array antenna,and the link budget analysis and evaluation are introduced.

Download or read book Large Deployable Satellite Antennas written by Baoyan Duan and published by Springer Nature. This book was released on 2020-06-29 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the innovative design, cable-net design and analysis, control, deployment, development and applications of large space-deployable antennas. Drawing on the authors’ own work in this field, it describes and analyzes various typical deployable antennas, membrane antennas and super-large space-assembled antennas, while chiefly focusing on mesh antennas due to their wide range of applications. It also investigates forming–finding design and the analysis of cable-truss structures for high-precision reflector antennas, as well as deployment process control and deployment reliability based on flexible multibody dynamic analysis. The book covers not only mechanical structure performance, but also electromagnetic performance realization and stability. Lastly, it proposes an electrical equivalent method for mesh reflector antennas and a coupling model for the structural displacement field and electrostatic field. Given the nature of its content, the book is intended for researchers, graduate students and engineers in the field of space antennas.

Book Synopsis Laser Satellite Communication by : William H. Mott IV
Download or read book Laser Satellite Communication written by William H. Mott IV and published by Bloomsbury Publishing USA. This book was released on 2000-01-30 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This introduction to the next generation of human telecommunications enterprise examines the development of laser satellite communications and describes its advantages over previous technologies. It looks at the development of the technology and the industry through wired and wireless media and presents the vision, promise, and challenges of free-space lasers. The book balances its focused consideration of the telecommunications industry and markets with practical thoughts on creating a business involved in the introduction of commercial laser satellite communications systems. Scholars, investors, venture capitalists, policy makers, and corporate leaders will find this to be a comprehensive and eye-opening bridge between the existing telecommunications industry and the opportunities of the next generation. The opening chapters introduce the concepts of Migration, Specialization, and Interconnectivity as solutions inherent in third generation laser-satellite communications. The high capacity of the optical spectrum invites migration of applications beyond the narrow RF spectra to the high frequencies of free-space laser beams. Migration stimulates specialization of voice and duplex at the lower, optimal RF spectra. The third generation—laser-wired space—focuses around global satellite interconnectivity between fiber optics and RF. The final chapters introduce a model business concept to pioneer the third generation. Several approaches to capitalization, organization, technology development, and business strategies provide an exciting stimulus for pragmatic approaches to commercial concepts.

Book Synopsis Antenna Arraying Techniques in the Deep Space Network by : David H. Rogstad
Download or read book Antenna Arraying Techniques in the Deep Space Network written by David H. Rogstad and published by John Wiley & Sons. This book was released on 2005-02-18 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to antenna Arraying in the Deep Space network Antenna arraying is the combining of the output from several antennas in order to improve the signal-to-noise ratio (SNR) of the received signal. Now implemented at the Goldstone Complex and other Deep Space Network (DSN) overseas facilities, antenna arraying provides flexible use of multiple antennas to increase data rates and has enabled NASA's DSN to extend the missions of some spacecraft beyond their planned lifetimes. Antenna Arraying Techniques in the Deep Space Network introduces the development and use of antenna arraying as it is implemented in the DSN. Drawing on the work of scientists at JPL, this timely volume summarizes the development of antenna arraying and its historical background; describes key concepts and techniques; analyzes and compares several methods of arraying; discusses several correlation techniques used for obtaining the combined weights; presents the results of several arraying experiments; and suggests directions for future work. An important contribution to the scientific literature, Antenna Arraying Techniques in the Deep Space Network * Was commissioned by the JPL Deep Space Communications and Navigation Systems (DESCANSO) Center of Excellence * Highlights many NASA-funded technical contributions pertaining to deep space communications systems * Is a part of the prestigious JPL Deep Space Communications and Navigation Series The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep space navigation and communications by disseminating state-of-the-art knowledge in key technologies.

Book Synopsis Introduction to Modern Instrumentation by : Dardo Oscar Guaraglia
Download or read book Introduction to Modern Instrumentation written by Dardo Oscar Guaraglia and published by Walter de Gruyter GmbH & Co KG. This book was released on 2014-01-01 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural hazards and anthropic activities threaten the human environment. The gathering of field data is needed so as to quantify the impact of such activities. To gather the necessary data researchers nowadays use a great variety of new instruments based on electronics. Yet, the working principles of this new instrumentation might not be well understood by some potential users. All operators of these new tools must gain proper insight so as to be able to judge whether the instrument is selected appropriately and functions adequately. This book attempts to demonstrate some characteristics that are not easy to understand by the uninitiated in the use of electronic instruments. The material presented in this book was prepared with the purpose of reflecting the technological changes that have occurred in environmental modern instrumentation in the last few decades. The book is intended for students of hydrology, hydraulics, oceanography, meteorology and environmental sciences. Basic concepts of electronics, special physics principles and signal processing are introduced in the first chapters in order to enable the reader to follow the topics developed in the book, without any prior knowledge of these matters. The instruments are explained in detail and several examples are introduced to show their measuring limitations. Enough mathematical fundamentals are given to allow the reader to reach a good quantitative knowledge.
