Book excerpt: This dissertation investigates in-situ, high-resolution radar imaging of dynamic targets using an ultra-wideband (UWB) radar. Three challenging classes of dynamic targets are investigated: wind turbines, vehicles, and small consumer drones. First, the measurement and processing methodologies are developed to capture the inverse synthetic aperture radar (ISAR) image of an operating horizontal-axis wind turbine. Measurement data of a small three-blade wind turbine are collected using a UWB radar, and the measured signatures are compared to simulation results based on physical optics. The backscattering phenomenology is examined in the sinogram, spectrogram, and ISAR image domains. The same methodologies are then applied to generate the in-situ ISAR imagery of an 18-blade windmill and a 1.7 MW utility-class wind turbine. Next, the radar signatures of a vertical-axis wind turbine are studied. Measurement and simulation are carried out for a 1.5 m tall Darrieus-type turbine model. Interpretation of the dominant backscattering mechanisms is carried out. Subsequently, the radar signatures of a 112 m tall turbine are examined using simulation. Second, wide-angle ISAR imaging of vehicles is investigated. Measurement data of moving vehicles are collected using a stationary roadside UWB radar. The generated baseline ISAR images show a clear distinction between different-sized vehicles. The images are further focused through motion compensation using a p-norm minimization. The resulting images are well focused and correspond closely to the physical dimensions of the vehicles. Third, the ISAR imaging of small consumer drones is considered. Laboratory measurement is conducted first, where the drones are rotated on a turntable and the backscatterered data are collected over a wide frequency band to form high-resolution images. The effects of frequency band, aspect, polarization, dynamic blade rotation, camera mount, and drone types are examined. Subsequently, ISAR imaging of in-flight drones, from data collected using a stationary UWB radar on the ground, is demonstrated. Finally, synthetic aperture radar (SAR) imaging using a small drone as the radar platform is explored. The entire system including a UWB radar, antennas, a camera, and a single-board computer fits on the small drone and is controlled through a Wi-Fi connection. Both the side-looking and downward-looking SAR scenarios are presented.

Available in PDF, EPUB and Kindle. Book excerpt: In 1995, James D. Taylor's Introduction to Ultra-Wideband Radar Systems introduced engineers to the theory behind a promising new concept for remote sensing. Since then, the field has undergone enormous growth with new applications realized and more applications conceptualized at a remarkable pace. However, understanding ultra-wideband (UWB) radar requires a new philosophical approach. Concepts such as radar cross section will have new meanings as range resolution becomes smaller than the target. Ultra-Wideband Radar Technology is a guide to the future of radar by an international team of experts. They present the problems, solutions, and examples of UWB radar remote sensing. Chapters discuss the theory and ideas for future systems development, and show the potential capabilities. The writers present concepts such as the differences between UWB and conventional radars, improving over-resolved target detection, receivers and waveforms, micropower systems, high power switching, and bistatic radar polarimetry. Finding comparable information elsewhere might require consulting hundreds of other books, technical journals, and symposium proceedings. Ultra-Wideband Radar Technology offers a unique opportunity to explore the theory, applications, and technology of UWB radar within a single source.

Available in PDF, EPUB and Kindle. Book excerpt: Radar-based imaging of aircraft targets is a topic that continues to attract a lot of attention, particularly since these imaging methods have been recognized to be the foundation of any successful all-weather non-cooperative target identification technique. Traditional books in this area look at the topic from a radar engineering point of view. Consequently, the basic issues associated with model error and image interpretation are usually not addressed in any substantive fashion. Moreover, applied mathematicians frequently find it difficult to read the radar engineering literature because it is jargon-laden and device specific, meaning that the skills most applicable to the problem's solution are rarely applied. Enabling an understanding of the subject and its current mathematical research issues, Radar Imaging of Airborne Targets: A Primer for Applied Mathematicians and Physicists presents the issues and techniques associated with radar imaging from a mathematical point of view rather than from an instrumentation perspective. The book concentrates on scattering issues, the inverse scattering problem, and the approximations that are usually made by practical algorithm developers. The author also explains the consequences of these approximations to the resultant radar image and its interpretation, and examines methods for reducing model-based error.

Book excerpt: Fast response transistors for ultrawideband (UWB) radar systems and faster computers have prompted novel approaches to theoretical descriptions of such signal systems and solutions to conventional radar problems. According to Astanin (Baltic Technical U., St. Petersburg) and Kostylev (Mozhaisky Military Academy of Space Engineering), UWB has entered a third wave of research interest this decade: the first being tracking of a radar target, and the next, steady oscillation transmission. After introducing definitional, modeling, and measurement issues, they probe target scattering, target responses, UWB signal processing, and design principles and mathematical modeling of UWB radar meters.

Available in PDF, EPUB and Kindle. Book excerpt: Through-the-wall radar imaging (TWRI) allows police, fire and rescue personnel, first responders, and defense forces to detect, identify, classify, and track the whereabouts of humans and moving objects. Electromagnetic waves are considered the most effective at achieving this objective, yet advances in this multi-faceted and multi-disciplinary technology require taking phenomenological issues into consideration and must be based on a solid understanding of the intricacies of EM wave interactions with interior and exterior objects and structures. Providing a broad overview of the myriad factors involved, namely size, weight, mobility, acquisition time, aperture distribution, power, bandwidth, standoff distance, and, most importantly, reliable performance and delivery of accurate information, Through-the-Wall Radar Imaging examines this technology from the algorithmic, modeling, experimentation, and system design perspectives. It begins with coverage of the electromagnetic properties of walls and building materials, and discusses techniques in the design of antenna elements and array configurations, beamforming concepts and issues, and the use of antenna array with collocated and distributed apertures. Detailed chapters discuss several suitable waveforms inverse scattering approaches and revolve around the relevance of physical-based model approaches in TWRI along with theoretical and experimental research in 3D building tomography using microwave remote sensing, high-frequency asymptotic modeling methods, synthetic aperture radar (SAR) techniques, impulse radars, airborne radar imaging of multi-floor buildings strategies for target detection, and detection of concealed targets. The book concludes with a discussion of how the Doppler principle can be used to measure motion at a very fine level of detail. The book provides a deep understanding of the challenges of TWRI, stressing its multidisciplinary and phenomenological nature. The breadth and depth of topics covered presents a highly detailed treatment of this potentially life-saving technology.

Available in PDF, EPUB and Kindle. Book excerpt: Ultra wideband (UWB)- synthetic aperture radars are emerging devices that are ideal for sensing and imaging applications in many special conditions such as monitoring subsurfaces, through-wall imaging, non-destructive characterization of materials, oil reservoir monitoring, weather forecasting, geo mapping, microwave holography for tissue imaging, and breast tomography to identify tumors. The exceptional characteristics of UWB radars, including high spatial resolution, low probability of interfering with other radio frequency (RF) signals, low power spectral density and compact size make them suitable for numerous applications. Moreover, their low power consumption allows them to operate on batteries, lending them to portable applications. Oil reservoir monitoring using UWB radar is a new trend in the oil and gas industry for reservoir management and improving production. Monitoring perforations'conditions in metal or concrete-cased oil wells can provide valuable information for oil well maintenance and process optimization. Moreover, observing steam chamber growth in a heavy oil reservoir using radar technology will provide feedback to control steam flow to enhance oil extraction in the steam assisted gravity drainage (SAGD) process. Radar imaging is a developing imaging modality for biomedical applications to study functional and pathological conditions of soft tissue. Radar imaging offers a safe, portable, cost-effective and near real-time imaging supplement for the non-invasive assessment of acute and chronic soft tissue conditions. Microwave imaging may turn out to be a simple and efficient method to perform breast imaging capable of providing adequate image resolutions for diagnosis. This thesis focused on the applications of UWB-synthetic aperture radar (SAR) systems for oil reservoir monitoring and breast tumor imaging; both applications share a requirement for high image resolution. The theory part investigates the design procedure for UWBSAR systems with specific range and cross-range resolutions. The effect of the pulse shape, bandwidth, integration angle, and signal-to-noise ratio (SNR) of the received pulse on the image resolution is comprehensively studied. To enhance the image resolution, pre-processing of the received pulses with envelope detection is proposed. Superluminal phenomenon and UWB pulse propagation in the near-field of an antenna is studied. The apparent superluminal pulse velocity is due to the pulse reshaping of the radiated pulse in the near-field of the antenna. The effect of pulse velocity on the quality of reconstructed images is demonstrated. The application part looks at the suitability of UWB-SAR for oil reservoir monitoring, such as perforation imaging in concrete- and metal-cased oil wells and steam chamber monitoring in heavy oil reservoir. High-quality images are reconstructed using a combination of UWB radar and SAR processing along with the proposed algorithms to improve image quality. The investigation includes positive image generation to enhance image sharpness, and near-field imaging procedure. Practical considerations for SAGD process monitoring such as power budget and heterogeneity analysis of a heavy oil reservoir using UWB radar are studied. The application of UWB-circular synthetic aperture radar (CSAR) for breast tumor imaging is also demonstrated. Tomographic image reconstruction was carried out using a time domain global back projection technique adapted to circular trajectory data acquisition. The suitability of this technique for breast tumor detection and imaging is demonstrated through experiments on a 3D printed breast phantom, developed based on a human breast MRI, which emulates the breast in terms of structures and their electrical properties. The measurement results demonstrated the utility of UWB-CSAR for breast tumor imaging.
