Available in PDF, EPUB and Kindle. Book excerpt: An authoritative work on Synthetic Aperture Radar system engineering, with key focus on high resolution imaging, moving target indication, and system engineering technology Synthetic Aperture Radar (SAR) is a powerful microwave remote sensing technique that is used to create high resolution two or three-dimensional representations of objects, such as landscapes, independent of weather conditions and sunlight illumination. SAR technology is a multidisciplinary field that involves microwave technology, antenna technology, signal processing, and image information processing. The use of SAR technology continues grow at a rapid pace in a variety of applications such as high-resolution wide-swath observation, multi-azimuth information acquisition, high-temporal information acquisition, 3-D terrain mapping, and image quality improvement.

Book Synopsis Wide Band Antenna Array for Synthetic Aperture Radar Applications by : May Abo Elhassan
Download or read book Wide Band Antenna Array for Synthetic Aperture Radar Applications written by May Abo Elhassan and published by GRIN Verlag. This book was released on 2022-07-07 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2020 in the subject Electrotechnology, , language: English, abstract: In this thesis, a PSO optimization algorithm is applied using a developed technique to synthesize the radiation patterns required for high-resolution land imaging SAR and satellite communications using planar rectangular or concentric circular arrays. The goal of the PSO algorithm is to get the excitation coefficients of the array elements, which are, then, Microstrip patch antennas with linear or circular polarization are proposed to construct the synthesized-beam arrays required for the considered application. A wide band rectangular patch antenna with U-slot is proposed for planar arrays with linear polarization. A square patch antenna with four truncated corners and four axial slots is designed for planar rectangular and circular arrays. Finally, a square patch antenna with two L-shaped slots inserted at diagonally opposite corners is designed for planar concentric circular arrays. Turnstile arrays of either dipole elements or U-slotted microstrip patch antennas excited with circulating phase shift are proposed to construct planar arrays with circular polarization for land-imaging SAR systems and satellite communications. Synthetic Aperture Radar (SAR) is used for remote sensing to create two-dimensional images of land covers on the earth’s surface. Such a land-imaging system has a great importance in many civilian and military applications. The SAR uses the radar antenna to scan a ground area to provide microwave images with fine spatial resolution. The SAR is typically mounted on an aircraft or spacecraft, and usually has a form of side-looking radar. It uses the Doppler and time delay information of the ground reflected wave to generate a two-dimensional image with the desired azimuth resolution (direction of motion) and range resolution (normal to the direction of motion), respectively. The SAR operation requires a physical antenna of radiation pattern with foot print of high aspect ratio and a mechanism capable of achieving beam steering and beam shaping. The SAR antenna array should be rigid, planar, deployable, and as lightweight as possible. A side-looking SAR system requires an antenna with a flat-topped beam pattern in the plane of the azimuth direction and a cosecant-squared beam shape in the plane of the range direction. For satellite communications with the ground stations, an isoflux beam is required for uniform coverage and continuity during the communication session.
Book Synopsis Modeling Backscattering Behavior of Vulnerable Road Users Based on High-Resolution Radar Measurements by : Abadpour, Sevda
Download or read book Modeling Backscattering Behavior of Vulnerable Road Users Based on High-Resolution Radar Measurements written by Abadpour, Sevda and published by KIT Scientific Publishing. This book was released on 2023-11-20 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the evolvement of autonomous driving technology, obtaining reliable 3-D environmental information is an indispensable task in approaching safe driving. The operational behavior of automotive radars can be precisely evaluated in a virtual test environment by modeling its surrounding, specifically vulnerable road users (VRUs). Such a realistic model can be generated based on the radar cross section (RCS) and Doppler signatures of a VRU. Therefore, this work proposes a high-resolution RCS measurement technique to determine the relevant scattering points of different VRUs.
Book Synopsis Multi-Antenna Synthetic Aperture Radar by : Wen-Qin Wang
Download or read book Multi-Antenna Synthetic Aperture Radar written by Wen-Qin Wang and published by CRC Press. This book was released on 2017-07-12 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthetic aperture radar (SAR) is a well-known remote sensing technique, but conventional single-antenna SAR is inherently limited by the minimum antenna area constraint. Although there are still technical issues to overcome, multi-antenna SAR offers many benefits, from improved system gain to increased degrees-of-freedom and system flexibility. Multi-Antenna Synthetic Aperture Radar explores the potential and challenges of using multi-antenna SAR in microwave remote sensing applications. These applications include high-resolution imaging, wide-swath remote sensing, ground moving target indication, and 3-D imaging. The book pays particular attention to the signal processing aspects of various multi-antenna SAR from a top-level system perspective. Explore Recent Extensions of Synthetic Aperture Radar Systems The backbone of the book is a series of innovative microwave remote sensing approaches developed by the author. Centered around multi-antenna SAR imaging, these approaches address specific challenges and potential problems in future microwave remote sensing. Chapters examine single-input multiple-output (SIMO) multi-antenna SAR, including azimuth and elevation multi-antenna SAR, and multiple-input multiple-output (MIMO) SAR. The book details the corresponding system scheme, signal models, time/phase/spatial synchronization methods, and high-precision imaging algorithms. It also investigates their potential applications. Introductory Tutorials and Novel Approaches in Multi-Antenna SAR Imaging Rigorous and self-contained, this is a unique reference for researchers and industry professionals working with microwave remote sensing, SAR imaging, and radar signal processing. In addition to novel approaches, the book also presents tutorials that serve as an introduction to multi-antenna SAR imaging for those who are new to the field.

This book was released on 2023-08-15 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radar target simulators (RTSs) deceive a radar under test (RuT) by creating an artificial environment consisting of virtual radar targets. In this work, new techniques are presented that overcome the rasterization deficiency of current RTS systems and enable the generation of virtual targets at arbitrary high-precision positions. This allows for continuous movement of the targets and thus a more credible simulation environment.
