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.

This book was released on 2018-02-16 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports on sparsity-based multipath exploitation methods for through-the-wall radar imaging. Multipath creates ambiguities in the measurements provoking unwanted ghost targets in the image. This book describes sparse reconstruction methods that are not only suppressing the ghost targets, but using multipath to one’s advantage. With adopting the compressive sensing principle, fewer measurements are required for image reconstruction as compared to conventional techniques. The book describes the development of a comprehensive signal model and some associated reconstruction methods that can deal with many relevant scenarios, such as clutter from building structures, secondary reflections from interior walls, as well as stationary and moving targets, in urban radar imaging. The described methods are evaluated here using simulated as well as measured data from semi-controlled laboratory experiments.

Download or read book Through the Wall Imaging Radar written by and published by . This book was released on 2003 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: This effort was established to develop a dual mode stepped frequency radar and advanced image recognition processing. The first mode would be used to image walls within a building. This imagery would allow a building to be remotely mapped. The second mode would be used to detect the presence of living people within the building. The task would then continue by working to integrate the imagery of the living people with the imagery of the building. A brassboard antenna array and radar electronics were integrated into a collapsing structure that weighs less than 20 pounds and is small enough to be carried by a single individual. The radar is capable of seeing through walls and forming images of the structure as well as detecting individuals at a range of 40 feet. The brassboard can be used to detect the motion of individuals through multiple interior walls using coherent scene subtraction. The images formed by the radar will improve tactical awareness in operational environments.

Download or read book Mimo Radar Through the Wall Imaging Techniques written by Evan Gebhardt and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a compelling need to both detect and localize targets through barriers. The ability to do this is advantageous for police, military, and search and rescue teams. Radar systems are capable of processing returns from targets through barriers where optical and thermal systems can fail. This thesis describes techniques for detecting and localizing targets through barriers. There is also a desire to minimize the size and complexity of the radar systems. This is because these radar systems are usually operated in hostile and harsh conditions. This need to reduce size and complexity leads to difficulties in localization and detection because cross range resolution can be a function of both aperture size and number of elements. These pitfalls can be overcome by well thought out imaging scenarios and signal processing techniques. By utilizing multiple views via a multiple-input-multiple-output (MIMO) radar configuration, data can be fused to create a clearer image about what is going on behind the barrier. This thesis addresses this technique as well as different mitigation techniques, such as a singular value decomposition of wavelet transform method to improve localization and detection of targets. A stepped frequency radar system was also utilized to detect moving targets through walls using Doppler shifts. Together, these techniques demonstrate methods that show a reduction in size and complexity of traditional through-wall radar systems while still providing accurate detection and localization.
