Available in PDF, EPUB and Kindle. Book excerpt: The original campus of the University of Michigan was nearly a perfect square about a half-mile along a side. A street-sized walk, appropriately called the Diag, runs diagonally across this square, connecting its southeast and northwest corners. In 1904 a new engineering building was either started or finished (I do not remember which) to house classrooms. When another engineering building was built on the expanded campus across the street from it many years later, the old building came to be known as West Engine, to distinguish it from the new East Engine. Old West Engine is (or maybe by now, was) a four-story, L-shaped structure that stood at the southeast corner of the original campus. It was built with an arch in it to straddle the Diag at the apex of the L. You walked over the Engineering Arch to get from one leg of the L to the other if you were inside the building, and you walked under it when you entered the campus from the southeast corner. Affixed to the masonry wall of the arch was a plaque I often noted in passing. It bore a quote attributed to Horace Greeley (1811-1872), who I did not know at the time was the founder, editor, and publisher of the New York Tribune. It said, simply, Young man, when theory and practice differ, use your horse sense. The suggestion seems worthy of an exclamation point instead of a period, but I do not remember if it had one.

Book excerpt: Two methods of measuring radar cross sections as small as 10 to the minus 10 power sq m are described. The first technique uses the return signal from a doppler radar. The second relates radar cross section to variation in VSWR produced by the target when placed in a waveguide. These methods were used to measure the cross section of mosquitoes. Results of these measurements at both X and Ku-bands are included. Calibration techniques are discussed for both methods of cross section measurement.

Available in PDF, EPUB and Kindle. Book excerpt: The leading text and reference on radar cross section (RCS) theory and applications, this work presents a comparison of two radar signal strengths. One is the strength of the radar bean sweeping over a target, the other is the strength of the reflected echo senses by the receiver. This book shows how the RCS "gauge" can be predicted for theoretical objects.

Download or read book Active Radar Cross Section Reduction written by Hema Singh and published by Cambridge University Press. This book was released on 2015-03-02 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: With this book practitioners responsible for analyzing, specifying or evaluating RCS imaging systems will be able to define performance limits using basic physical and mathematical principles. Information on instrumentation systems for acquiring data and two new chapters on applications of new techniques are included. The emphasis of the book is on imaging as applied to radar cross-section measurements. With it the reader will learn how to use the latest techniques to perform RCS imaging in laboratory or outdoor test ranges. This book is suitable for self-study or for use in a short course for practising engineers.
Download or read book A Minimum Range Criterion for RCS Radar Cross Section Measurements of a Target Dominated by Point Scatterers written by B. M. Welsh and published by . This book was released on 1983 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis develops a minimum range criterion for radar cross-section measurements by neglecting the phase of the incident field at the target and considering only the amplitude distribution. In contrast to the traditional minimum range criterion, developed for a flat target characterized by specular reflection, the target examined in this thesis is characterized by a number of independent point scatterers located on the target surface. Instead of enforcing point by point accuracy, accuracy of the average target RCS is required, averaging over a number of measurements. The location of the point scatterers on the target are described probabilistically; the expected average measured RCS versus target range is calculated, and compared to results of a Monte-Carlo simulation. The traditional minimum range criterion is compared to the new minimum range criterion. The traditional minimum range criterion, based on phase uniformity across the target, requires minimum measurement ranges that are much larger than those ranges dictated by the new minimum range criterion for targets dominated by point scattering.

This book was released on 2018-10-18 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first Small Expendable Deployer System (SEDS-1), a tethered satellite system, was developed by NASA and launched March 29, 1993 as a secondary payload on a United State Air Force (USAF) Delta-2 launch vehicle. The SEDS-1 successfully deployed an instrumented end-mass payload (EMP) on a 20-km nonconducting tether from the second stage of the Delta 2. This paper describes the effort of NASA Langley Research Center's Antenna and Microwave Research Branch to provide assistance to the SEDS Investigators Working Group (IWG) in determining EMP dynamics by analyzing the mission radar skin track data. The radar cross section measurements taken and simulations done for this study are described and comparisons of the measured data with the simulated data for the EMP at 6 GHz are presented.

Download or read book Radar Cross Section Measurements written by Robert B. Dybdal and published by . This book was released on 1986 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamentals of radar cross section measurements are reviewed. Measurement facilities, including the present research activities on compact range techniques, are then described. Instrumentation radars have benefited from both wide bandwidth electronics and digital processing capabilities. Fourier transform techniques, in particular, provide both additional information on target scattering, and increased measurement accuracy by isolating the target from radar returns from the measurement facility. The frequency coverage has also been extended to include millimeter wave frequencies. Achievable accuracy is important in any measurement program, and those factors that limit the accuracy of radar cross section measurements are discussed.
