The book presents principles of operation of radar and radionavigation systems. The group of radar systems includes: primary and secondary radiolocations, bistatic and multistatic systems. They are illustrated with relevant examples of calculation and applications. The issues of increasing the range of the radar systems are presented together with the matched filtering of the used signals. Other discussed issues are methods for eliminating interfering signals and researching methods of 3D space. Various methods of the monopulse radiolocation are presented in Chapter 12. In Chapters 13–18 terrestrial and satellite radionavigation systems are under discussion. The terrestrial systems are: Loran C, Decca Navigator and Omega. The TRANSIT is an example of a hyperbolic satellite system. The stadiometric systems GPS, GLONASS, GALILEO, BeiDou, IRNSS and QZSS are discussed together with differential systems augmentating of them. The ILS, MLS and TLS supporting the landing of aircrafts are discussed in Chapter 17. The prospects for replacing of them with satellite systems augmentated by appropriate reference ground-based stations (GBAS) are also analyzed. Various beacons and ranging devices used in aviation are described in the Chapter 18. This book is intended primarily for students and engineers interested in radar, radionavigation and aerospace engineering.

Designed for those who make their living on the sea or who navigate offshore for recreation, this comprehensive textbook introduces the mariner to each navigation and communication system and outlines its uses and limitations in practical application. An introduction to the basic theory of radio waves and how they affect system use is followed by descriptions of the various types of equipment and how they function. Especially useful for the navigator are discussions of radio direction finding systems, including radar beacons; hyperbolic radio navigation systems; satellite navigation systems, including the Global Positioning System and the Global Navigation Satellite System; hydrosonic systems; radar; and Automatic Radar Plotting. The sections on communications cover all systems in application in the marine field, including the Global Maritime Distress Safety System. Also discussed are shipboard control systems, including compasses and steering systems, and integrated bridge systems. This book also provides excellent preparation for those studying for a license examination or serving aboard ships in the military.

This completely updated second edition of an Artech House classic provides a thorough introduction to the basic principles of electromagnetic wave propagation of radio frequencies in real-world conditions, fully updated by including new achievements in theory and technology. It serves as an invaluable daily reference for practitioners in the field and as a complete, organized text on the subject. This comprehensive resource covers a wide range of essential topics, from the classification of radio waves, electromagnetic wave theory, and antennas for RF radio links, to the impact of the earth surface on the propagation of ground waves, atmospheric affects in radio wave propagation, and radio wave reception. The book explores the propagation of the ground radio waves, namely the waves that propagate in vicinity of the earth's surface (e.g., guided by that interface), without involvement of any atmospheric effects. Specifics of the high-frequency (HF) radio propagation due to reflections from ionospheric layers is studied, based on commonly used models of the ionospheric vertical profiles. Scattering of the radio waves of UHF and higher frequency bands from the random variations of the tropospheric refraction index (from tiny air turbulences) are also considered by using the principles of statistical radio-physics. Analysis of propagation conditions on real propagation paths, including analysis of the power budget of the VHF/UHF link to assure its stability (percentage of availability within observation time frame), terrestrial, broadcast, mobile, and satellite RF links are presented. The engineering design of the cellular networks, including LTE 4G, 5G and upcoming higher generations is explored. HF propagation predictions for extremely long-range links design for commercial and military applications are explained. Packed with examples and problems, this book provides a theoretical background for astrophysical, aeronomy and geophysical instrumentation design.

Here's a unique new resource that offers you a solid understanding of the fundamental theory, operation principles and applications of short-range frequency modulated continuous wave (FM CW) radar. You learn how to choose the structural scheme of short-range FM radar, and determine the optimal algorithm of useful signal processing necessary for ensuring the technical characteristic of radar. Moreover, this practical reference shows you how to ensure the minimum level of radar signal parasitic amplitude, calculate modulation signal distortion, and compensate for nonlinear distortion.
