This book describes the application of polarimetric synthetic aperture radar to earth remote sensing based on research at the NASA Jet Propulsion Laboratory (JPL). This book synthesizes all current research to provide practical information for both the newcomer and the expert in radar polarimetry. The text offers a concise description of the mathematical fundamentals illustrated with many examples using SAR data, with a main focus on remote sensing of the earth. The book begins with basics of synthetic aperture radar to provide the basis for understanding how polarimetric SAR images are formed and gives an introduction to the fundamentals of radar polarimetry. It goes on to discuss more advanced polarimetric concepts that allow one to infer more information about the terrain being imaged. In order to analyze data quantitatively, the signals must be calibrated carefully, which the book addresses in a chapter summarizing the basic calibration algorithms. The book concludes with examples of applying polarimetric analysis to scattering from rough surfaces, to infer soil moisture from radar signals.
Bistatic radars have been a focus of study since the earliest days of radar research. Despite this, until recently only a few bistatic systems have crossed the experimental study threshold and, consequently, there is little known about them compared to their monostatic counterparts. Now, however, there is fast growing interest in bistatic radar, due to its importance in the development of defence, remote sensing, aerospace, meteorological and navigation application fields, as well as its unique peculiarities. These include: covert operational ability relevant to the receiver position, counter-stealth ability, and a potentially reduced cost as one transmitter can be used to send information to several receivers. With contributions from international experts working with bistatic radar, this book, the first in a series on bistatic radar, provides an introduction to the technology, covering information on basic principles and design. Starting with a detailed look at monostatic radar, examining the development of the field as a whole, the book then goes on to: introduce the classical aspects of bistatic radar such as geometry, power budget and resolution; present an in depth analysis of bistatic scattering of electromagnetic waves; provide an overview of the bistatic radar potential which follows from their bistatic nature; discuss forward scattering radar; investigate forward scattering radar for air targets detection and tracking; set out an experimental study of real world forward scattering radar. Bistatic Radars: Principles and Practice gives an up-to-date overview of this important technology for practising engineers and researchers involved in the design andimplementation of bistatic radar in a range of industries. It is also a valuable reference for advanced students taking special courses in radar technology.

Expanding the range of antenna frequency is the main objective of this book. Solutions proposed are based on the development of new theoretical methods for analyzing and synthesizing antennas. The book shows that concentrated capacitive loads connected along linear and V-antennas provide a high level of matching with a cable over a wide frequency range and improves directional characteristics of antennas, i.e. increases the communication distance. New theoretical methods are proposed for analysis and synthesis of antennas under consideration: 1) method of calculating directional characteristics of radiators with a given current distribution, and 2) method of electrostatic analogy for calculating mutual and total fields of complex multi-element radiating structures. These methods allow us to obtain optimal directional characteristics for director-type antennas (arrays of Yagi-Uda) and log-periodic antennas with concentrated capacitances and show that use of capacitors makes it possible to extend the frequency range of the director antennas and to decrease dimensions of the log-periodic antennas Multi-element (flat and three-dimensional) self-complementary antennas with different variants of connecting generator poles and cable wires to antenna elements are proposed, which improves the matching with a cable. Characteristics of flat structures are compared with characteristics of volume structures: conical, parabolic, and located on a pyramid edges. The book describes new versions of transparent antennas, antennas for cellular communication, multi-tier and multi-radiator antennas, and much more.
Over the last ten years, the numbers of unmanned air vehicles (UAVs) or "drones" have changed from being just a few specialist systems, used for scientific data gathering and military purposes, to them proliferating in huge numbers. They are used across a broad range of different leisure, commercial and military activities. UAVs can be used for: movement of items in factories for manufacturing, passenger and freight transportation, can take various roles in the agriculture and forestry industries (dispensing seeds, watering and monitoring crops), remote sensing for the oil and gas industries, traffic flow monitoring, support of emergency services, hobbies, security, military and many other applications. The expansion in the use of unmanned air vehicles has come about due to the development of low cost, high performance stable platforms, employing equally low-cost communication and navigation systems supplemented by simple to use software and interfaces. Therefore, there is a need to be able to monitor the rapidly changing use of airspace, especially at low and normally neglected altitudes to ensure UAVs do not compromise safety or are used for malicious purposes. Radar is the only sensor able to perform this function on a 24-hour, all weather, wide-area basis. This book, concerned with radar surveillance of UAVs, has been compiled using contributions from the leading experts around the world to create a single body of knowledge on this important, yet still emerging, topic. It is aimed at advanced students and researchers with an interest in radar systems.
