Available in PDF, EPUB and Kindle. Book excerpt: The report describes the implementation, procedure, and results of the Multipurpose Foliage Penetration Radar (M-FOPEN) conducted by the 25th Infantry Division. Maximum ranges of detection were determined for the M-FOPEN operating in various types of terrain and foliage, and probability of detection calculated for each range, target, and foliage combination. These tests demonstrated the capability of the M-FOPEN to penetrate up to 700 meters of foliage and detect moving targets, with a negligible false alarm rate. A tactical exercise was conducted during which the M-FOPEN and the standard AN/ PPS-5 Ground Surveillance Radars were deployed and the detection performance and false alarm rates of each compared. Detection experiments were performed with the M-FOPEN using a helicopter (AH-1G) as the target to determine the doppler signature of the aircraft. These demonstrated that a unique doppler signature does exist for helicopters and the helicopters are detectable using the M-FOPEN even though the path between the radar and the aircraft is blocked by foliage.

This book was released on 1986 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book sets out to explain the basic principles of radar and, where applicable, historical aspects of the evolution of these principles are dealt with. The study, while underlining the significance of the cavity magnetron, purposely restricts itself to the pre-cavity magnetron era of radar.
Download or read book Ultra wideband Radar Technology written by James D. Taylor and published by CRC Press. This book was released on 2018-10-03 with total page 442 pages. 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.

Download or read book Foliage Penetration FOPEN Radar Detection of Low Flying Aircraft written by and published by . This book was released on 1974 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes detection experiments performed with the Foliage Penetration (FOPEN) Radar operating at 140 MHz in which the target was a helicopter flying nap-of-the-earth (NOE). Preliminary experiments performed in Hawaii during the user evaluation of the FOPEN system demonstrated the ability of this radar to detect helicopters flying NOE using foliage and terrain for cover. A series of experiments at Aberdeen Proving Ground were made to establish the detection ranges through foliage for a single UH-1 helicopter. Additional measurements of the radar cross section of the UH-1 on the ground were taken using the LWL Airborne Foliage Penetration Radar, and are also reported. The report concludes with a theoretical analysis of the propagation losses affecting the detection of aircraft flying NOE by radars operating at frequencies of from 100 to 10,000 MHz.
Download or read book Introduction to Synthetic Aperture Radar Using Python and MATLAB written by Lee Andrew (Andy) Harrison and published by Artech House. This book was released on 2022-08-31 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive introduction to synthetic aperture radar (SAR) is a practical guide to the analysis, simulation, and design of SAR systems. The video eBook uses constructive examples and real-world collected datasets to demonstrate image registration and autofocus methods. Both two- and three-dimensional image formation algorithms are presented. Hardware, software, and environmental parameters are used to estimate performance limits for SAR operation and utilization. A set of Python and MATLAB software tools is included and provides you with an effective mechanism to analyze and predict SAR performance for various imaging scenarios and applications. Examples which use the software tools are provided at the end of each chapter to reinforce critical SAR imaging topics such as clutter-to-noise ratio, mapping rate, spatial resolution, Doppler bandwidth, pulse repetition frequency, and coherency. This is an excellent resource for engineering professionals working in areas of radar signal processing and imaging as well as students interested in studying SAR.
