Paperback. Etat : New. Print on Demand. This book delves into the fascinating world of wireless direction finding, a technique that utilizes the properties of electromagnetic waves to determine the location of distant transmitters. The author traces the evolution of this technology from its early experimental origins, exploring the work of pioneers like Hertz, Marconi, and Zenneck, who sought to concentrate transmitted power into beams. The book highlights the transition from basic directional transmission for economic reasons to the development of precise directive properties for position finding and navigation. It examines the similarities between visual and wireless methods of direction finding, emphasizing the limitations of visual methods in darkness or fog. The book explains the fundamental principles of wave propagation and explores the use of both open and closed aerial systems to achieve directionality. It dives into the theoretical underpinnings of different systems like the rotating frame, the Bellini-Tosi system, and the Robinson system, outlining the challenges and solutions related to vertical and direct reception. The book also delves into the complexities of night effect, a phenomenon that can distort bearings due to atmospheric conditions. Through a blend of historical context, technical explanations, and practical applications, the author provides a comprehensive exploration of the art and science of wireless direction finding. This book offers valuable insights into a vital technology that has played a crucial role in navigation, communication, and warfare, revealing the ingenuity and innovation behind a field that continues to shape our world. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N� de r�f. du vendeur 9781333145507_0
