LiDAR is one of many active sensor technologies that uses electromagnetic radiation. Operating in the optical and infrared wavelengths, it is similar to more-familiar passive EO/IR sensor technology. It is also similar to radar in that it uses reflected electromagnetic radiation emitted by the sensor. LiDAR is commonly used for making high-resolution maps and has applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping, and laser altimetry. It is also being used for control and navigation of some autonomous cars. The first part of LiDAR Technologies and Systems introduces LiDAR and its history, and then covers the LiDAR range equation and the link budget (how much signal a LiDAR must emit in order to get a certain number of reflected photons back), as well as the rich phenomenology of LiDAR, which results in a diverse array of LiDAR types. The middle chapters discuss the components of a LiDAR system, including laser sources and modulators, LiDAR receivers, beam-steering approaches, and LiDAR processing. The last part covers testing, performance metrics, and significant applications, including how to build systems for some of the more popular applications.

Tactical Persistent Surveillance Radar with Applications introduces technologists to the essential elements of persistent surveillance of tactical targets from both a hardware and software point of view, using simple Mathcad, Excel and Basic examples with real data. It is based on the type of surveillance done by drones like Scan Eagle, Predator, Reaper, Global Hawk, and manned aircraft like U-2, ASTOR, and JSTARS as well as spacecraft. The general topic is cellphone and datalink intercept, ground moving target radar, synthetic aperture radar, navigation, tracking, electronic scanning and cueing electro-optical sensors for activity based surveillance. Examples are taken from a wide range of technologies and techniques including passive detection, radar detection, antenna monopulse, active electronic scanned antennas (AESA), moving target tracking (MTT), motion compensation, tactical target spectral characteristics, moving target detection (MTI), space time adaptive processing (STAP), synthetic aperture radar (SAR) imaging, change detection (CCD), and synthetic monopulse. Over 120 example applications programs are included in the appendices and as downloads as well as over 100 SAR and GMTI raw IQ data files. These allow the curious to experiment with their own parameters and notions to achieve a greater understanding of the underlying behaviors. Based on the author's 55-year experience in engineering design, leadership, teaching and consulting, this book is an essential text for researchers, advanced students and technologists working in radar and related fields in computing and aerospace system design.

Synthetic Aperture Radar (SAR) is critical for remote sensing. It works day and night, in good weather or bad. Bistatic SAR is a new kind of SAR system, where the transmitter and receiver are placed on two separate platforms. Bistatic SAR is one of the most important trends in SAR development, as the technology renders SAR more flexible and safer when used in military environments. Imaging is one of the most difficult and important aspects of bistatic SAR data processing. Although traditional SAR signal processing is fully developed, bistatic SAR has a more complex system structure, so signal processing is more challenging. Focusing on imaging aspects of bistatic SAR signal processing, this book covers resolution analysis, echo generation methods, imaging algorithms, imaging parameter estimation, and motion compensation methods. The book is ideal for researchers and engineers in SAR signal and data processing, as well as those working in bistatic and multistatic radar imaging, and in the radar sciences. Graduate students with a background in radar who are interested in bistatic and multistatic radar will find this book a helpful reference. * Gives a general and updated framework for image formation using signal processing aspects * Starts with an introduction to traditional SAR before moving on to more advanced topics * Offers readers a range of exhaustive tools to process signals and form images * Provides a solid reference for the imaging of other complicated SAR * Sample image synthesis exercises are available from the book's companion site

This second of three volumes in the Principles of Modern Radar series offers a much-needed professional reference for practicing radar engineers. It provides the stepping stones under one cover to advanced practice with overview discussions of the most commonly used techniques for radar design, thereby bridging readers to single-topic advanced books, papers, and presentations. It spans a gamut of exciting radar capabilities from exotic waveforms to ultra-high resolution 2D and 3D imaging methods, complex adaptive interference cancellation, multi-target tracking in dense scenarios, multiple-input, multiple-output (MIMO) and much more. All of this material is presented with the same careful balance of quantitative rigor and qualitative insight of Principles of Modern Radar: Basic Principles. Each chapter is likewise authored by recognized subject experts, with the rigorous editing for consistency and suggestions of numerous volunteer reviewers from the radar community applied throughout. Advanced academic and training courses will appreciate the sets of chapter-end problems for students, as well as worked solutions for instructors. Extensive reference lists show the way for further study.

This book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms. It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then explains various methods and the emerging trends followed in this area of study. The RCS estimation of phased array including the mutual coupling effect is also presented in detail in the book. The active RCS reduction is carefully touched upon through the performance of phased arrays, sidelobe cancellers and mitigation of multipath effect. Providing information on various adaptive algorithms like least mean square (LMS), recursive least square (RLS) and weighted least square algorithms, the authors also mention the recent developments in the area of embedded antennas, conformal load bearing antenna, metamaterials and frequency selective surface (FSS) based RCS reduction.

Active (imaging radar) and passive (radiometer) microwave systems are increasingly used for Arctic ecological research. Unfortunately, until now ecologists interested in remote sensing often lacked access to the full suite of physical and analytical techniques of microwave systems, data processing, and ecological applications because a suitable reference book did not exist. Arctic Ecological Research from Microwave Satellite Observations answers this demand by summarizing the main microwave satellite applications for Arctic ecological research. This book is invaluable to specialists with a background in microwave techniques, as well as to other ecologists interested in applications of microwave active and passive remote sensing for tundra, boreal forest, and Arctic sea-ice habitat and marine mammal studies. It presents a brief introduction to Arctic ecological problems, the role of satellite sensing for monitoring Arctic ecosystems, and related data processing applications. The volume then examines results of Arctic sea-ice habitat studies using OKEAN-01 satellite data, then provides a comparative analysis of multisensor satellite monitoring of habitat using OKEAN-01, SSM/I and AVHRR satellite instruments. It also describes the evaluation of relative information content of ALMAZ-1, ERS-1, JERS-1 SAR, and Landsat-TM data for identifying wet tundra habitats. The book concludes with results of sensitive boreal forest type detection to monitor potential impacts of climate change on boreal forest structure.
