This unique book brings together RF Engineering and Optical Integration in terrestrial fixed and mobile networks, space networks and sub orbital communication systems (Low Altitude Platforms and High-Altitude Platforms). It is written specifically to help optical engineers to understand RF engineering and RF engineers needing to understand the optical technologies used in fixed and mobile networks, including local and long-distance fiber, free space terrestrial optical point to links, earth to space and space to earth links and inter satellite and inter-constellation cross connect. The book shows you how to mix and match RF and optical efficiently and explains how to repurpose terrestrial RF and terrestrial optical for space deployment. You’ll learn how to decide whether to use an RF or optical link; how to calculate an RF and optical link budget; how to interface an optical signal to an RF bearer – and vice versa; how to multiplex RF and optical signals in guided and unguided media; and much more. This is a must-have book for practicing RF engineers, optical engineers, and planners of satcom and terrestrial networks, supply chain partners to 5G/satellite RF/optical integrations needing understanding of problems and solutions. | |

 Название: Power Electronics: A First Course: Simulations and Laboratory Implementations, 2nd Edition
Автор: Ned Mohan, Siddharth Raju
Издательство: Wiley
Год: 2023
Страниц: 352
Язык: английский
Формат: epub
Размер: 57.0 MB
Enables students to understand power electronics systems, as one course, in an integrated electric energy systems curriculum. Power Electronics A First Course provides instruction on fundamental concepts related to power electronics to undergraduate electrical engineering students, beginning with an introductory chapter and moving on to discussing topics such as switching power-poles, switch-mode DC-DC converters, and feedback controllers. The authors also cover diode rectifiers, power-factor-correction (PFC) circuits, and switch-mode dc power supplies. Later chapters touch on soft-switching in dc-dc power converters, voltage and current requirements imposed by various power applications, dc and low-frequency sinusoidal ac voltages, thyristor converters, and the utility applications of harnessing energy from renewable sources. This textbook focuses on power electronic systems as one of the topics in an integrated electric energy systems curriculum consisting of power electronics, power systems, and electric machines and drives. This textbook follows a top-down systems-level approach to power electronics to highlight interrelationships between these subfields within this curriculum, and is intended to cover both the fundamentals and practical design in a single-semester course. | |

 Название: A Robotic Framework for the Mobile Manipulator: Theory and Application
Автор: Nguyen Van Toan, Phan Bui Khoi
Издательство: CRC Press
Серия: Artificial Intelligence and Robotics Serie
Год: 2023
Страниц: 116

Формат: pdf (true)
Размер: 29.8 MB
By proposing and forming a mobile manipulator for modern multi-floor buildings, A Robotic Framework for the Mobile Manipulator: Theory and Application helps readers visualize an end-to-end workflow for making a robot system work in a targeted environment. From a product-oriented viewpoint, this book is considered as a bridge from theories to real products, in which robotic software modules and the robotic system integration are mainly concerned. In the end, readers will have an overview of how to build and integrate various single robotic modules to execute a list of designed tasks in the real world, as well as how to make a robot system work independently, without human interventions. With references and execution guidelines provided at the end of each chapter, the book will be a useful tool for developers and researchers looking to expand their knowledge about the robotics and the robotic software. Single robotic modules and the system integration are then conducted on the Robot Operating System 2 (ROS2) and presented in remaining chapters as follows: in Chapter 2, a task-oriented approach is used to propose hardware and software modules for a robot system. | |

 Название: Adaptive Radar Detection: Model-Based, Data-Driven and Hybrid Approaches
Автор: Angelo Coluccia
Издательство: Artech House
Год: 2022
Страниц: 235
Язык: английский
Формат: pdf (true)
Размер: 30.3 MB
This book shows you how to adopt data-driven techniques for the problem of radar detection, both per se and in combination with model-based approaches. In particular, the focus is on space-time adaptive target detection against a background of interference consisting of clutter, possible jammers, and noise. It is a handy, concise reference for many classic (model-based) adaptive radar detection schemes as well as the most popular Machine Learning techniques (including deep neural networks) and helps you identify suitable data-driven approaches for radar detection and the main related issues. You’ll learn how data-driven tools relate to, and can be coupled or hybridized with, traditional adaptive detection statistics; understand fundamental concepts, schemes, and algorithms from statistical learning, classification, and neural networks domains. The book also walks you through how these concepts and schemes have been adapted for the problem of radar detection in the literature and provides you with a methodological guide for the design, illustrating different possible strategies. You’ll be equipped to develop a unified view, under which you can exploit the new possibilities of the data-driven approach even using simulated data. | |

The video eBook uses constructive examples and real-world collected datasets to demonstrate image registration and autofocus methods. Both two- and three-dimensional image formation algorithms are presented. Hardware, software, and environmental parameters are used to estimate performance limits for SAR operation and utilization. A set of Python and MATLAB software tools is included and provides you with an effective mechanism to analyze and predict SAR performance for various imaging scenarios and applications. Examples which use the software tools are provided at the end of each chapter to reinforce critical SAR imaging topics such as clutter-to-noise ratio, mapping rate, spatial resolution, Doppler bandwidth, pulse repetition frequency, and coherency. This is an excellent resource for engineering professionals working in areas of radar signal processing and imaging as well as students interested in studying SAR. The tool suite is written in the Python and MATLAB programming languages and gives the reader a mechanism to generate SAR images, predict the performance of SAR systems for various applications, and analyze images resulting from different scenarios. | |
