Radio And Communications

In this film, you’ll learn everything you need to know about getting started and on the air with radio communications.

This book presents an in-depth and up-to-date overview of the full range of wireless and mobile technologies that we rely on every day. The book includes everything from digital cellular mobile radio and evolving personal communication systems to wireless data and wireless networks.

The ARRL Handbook for Radio Communications is widely recognized as being the standard reference among radio amateurs and other technologists - experimenters, engineers and students. The fields of radio and electronics are constantly evolving, and no other publication provides as accurate a snapshot of the state of the art as The ARRL Handbook.

A practical guide to the principles of radio communications for both civilian and military applications
In this book, the author covers both the civilian and military uses of technology, focusing particularly on the applications of radio propagation and prediction. Divided into two parts, the author introduces the basic theory of radio prediction before providing a step-by-step explanation of how this theory can be translated into real-life applications. In addition, the book presents up-to-date systems and methods to illustrate how these applications work in practice. This includes systems working in the HF bands and SHF. Furthermore, the author examines the performance of these systems, and also the effects of noise, interference and deliberate jamming, as well as the performance of jamming, detection and intercept systems. Particular attention is paid to the problems caused by Radio Controlled Improvised Explosive Devices (RCIEDs).

The wave theory foundations of today's radio occultation techniquesForty years ago, the premier radio occultation problem was how to profile the atmosphere and radius of Mars using signals sent by the Mariner 4 spacecraft. Researchers then could rely on ray theory-based techniques for accurate analysis of the thin, uniform Martian atmosphere. Today's radio occultation challenges mostly involve communications platforms-and related data, instrument systems, and applications-in the Earth's own atmosphere.
