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.

Excerpt from Phase Dependence in Radar Cross Section Measurements A new measurement and analysis technique to isolate the background signals present in radar cross section measurements is presented. By definition the measured ros of a target is independent of the measured phase, but it is not independent of the phase difference between the theoretically correct signal and the background error signals present in the measurements. By varying the phase of the theoretical signal and holding the phase of the error signal constant, one can separate these two components. In the calibration model, where the radar cross section of the calibration target is known, the error signals can be removed from the measurements to obtain an accurate system calibration. When the radar cross section of the target is unknown, only error signals with a constant phase can be removed from the measurements. Error signals that vary in - phase with the theoretical signal will introduce a bias that increases the uncertainty of the measurements.

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.

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.

The book is a major extention of a chapter on bistatic radar written by the author for the Radar Handbook 2/e by Merrill Skolnick. It provides a history of bistatic systems that points out to potential designer the applications that have worked and the dead ends not worth pursuing. The text reviews the basic concepts and definitions and explains the mathermatical development of relationships such as gemometry, Ovals of Cassini, dynamic range, isorange and isodoppler contours, target doppler and clutter spread.

Electromagnetic Scattering is a collection of studies that aims to discuss methods, state of the art, applications, and future research in electromagnetic scattering. The book covers topics related to the subject, which includes low-frequency electromagnetic scattering; the uniform asymptomatic theory of electromagnetic edge diffraction; analyses of problems involving high frequency diffraction and imperfect half planes; and multiple scattering of waves by periodic and random distribution. Also covered in this book are topics such as theories of scattering from wire grid and mesh structures; the electromagnetic inverse problem; computational methods for transmission of waves; and developments in the use of complex singularities in the electromagnetic theory. Engineers and physicists who are interested in the study, developments, and applications of electromagnetic scattering will find the text informative and helpful.
