Interest in the applications of ultrawideband (UWB) radar systems is increasing rapidly all over the world. This is evident from the number of monographs recently published on the subject and from the many papers presented at international conferences on the general problems involved in UWB radar and on its promising new applications. Conventional (classical) methods seem to have exhausted their potential and studies in the field are undergoing a profound change. This book presents some of the novel approaches to radar system analysis now being investigated. A good source of information on UWB signals is their structural analysis in the time domain. This allows a greater understanding of the specific features of UWB radar systems, such as the properties of receiving and transmitting antennas, and various characteristics of near- and far-range target scattering fields. It is shown how the systematic application of numerical procedures can provide new results in the evaluation of UWB radar target responses. The authors do not try to cover all of the possible solutions to the problem of multidimensional representation of target responses; rather they aim to give a general understanding of the techniques of confluent analysis, computer holography and adaptive synthesis of antenna apertures. These methods have great potential for solving conventional radar problems in target detection and recognition, and they are sure to stimulate the use of UWB signals in many fields such as subsurface probing and ecological monitoring.

Accuracy and consistency are essential to success in manufacturing, and the technology of precision measurement is fully explained and illustrated in this important book. Throughout, the author accompanies illustrations of the devices with descriptions of how they are used in industry. Both apprentice and practicing engineers will discover a vast amount of new material that can be applied to virtually any imaginable measurement or calibration task.

During the 1980s, the worldwide interest in electromagnetic compatibility (EMC) grew rapidly with the introduction of legislation to control the growing interference problems generated by the increased use of electronic equipment in industry and in the home. The European directive harmonizing EMC measurements gave particular impetus to manufacturers and importers of electrical and electronic equipment in Europe to understand EMC design techniques and verification procedures. This book explains how equipment can be verified by testing. It discusses the nature of EMC standards world wide and describes in detail testing methods and their conduct and accuracy. In addition to standard EMC testing, topics including electrostatic discharge, nuclear electromagnetic pulse and lightning are also discussed. In the broad span of its subject matter, the interests of equipment manufacturers, EMC test engineers, project managers and company administrators are addressed. The testing of both military and commercial electronic equipment is covered. Particular emphasis is placed on the nature of EMC test equipment and how to use it to make reliable measurements.

RECENT CASTASTROPHIC STRUCTURAL FAILURES, OCCURING ACROSS MANY INDUSTRIES, HIGHLIGHT THE NEED FOR SOCIETY TO RELATE RISK MORE EXPLICITLY WITH INSPECTION PROGRAMS.

The need to measure electrical power is common to many branches of science and engineering. This book presents a wide-ranging survey of the many types of radio-frequency and microwave power meter and the techniques which are used for calibrating and intercomparing them. The frequency range is 1 MHz to 200 GHz. The first of the sixteen chapters considers the fundamentals. Four chapters are then devoted to the subject of calorimetry, which forms the basis of the majority of primary standards for power measurement. A further five chapters describe the various types of non-calorimetric power meter, which include not only the commonly used thermistor, thermoelectric and diode types, but also force-operated instruments and a considerable number of miscellaneous devices. Calibration and intercomparison methods are covered in three closely linked chapters which treat respectively the basic techniques, the use of reflectometers for power meter calibration, and the problems associated with connectors and adapters. In the last three chapters a mixture of topics is covered. First a concise survey of pulsed power measurements is presented. Attention is then given to the topics of voltage and current measurement, which are closely related to power measurement. Finally, the subject of the international intercomparison of standards is discussed and the results of some of the more important intercomparison exercises are summarised.

Starting with the useful concept of an elementary integral defined (axiomatically) on a family of elementary functions, this treatment examines the general theory of the integral, Lebesque integral in n space, the Riemann-Stieltjes integral, and more. "The exposition is fresh and sophisticated, and will engage the interest of accomplished mathematicians." - Sci-Tech Book News. 1966 edition.

In diesem Buch wird die Auswertung von Messdaten mit ihren Unsicherheiten fur die Anwendung im Physikalischen Praktikum dargestellt. Fur die wesentlichen Typen von Messaufgaben findet der Leser eine Zusammenstellung aller noetigen Formeln zur Bestimmung des Bestwertes und der kombinierten und erweiterten Messunsicherheit sowie praktische Hinweise fur die Ermittlung von Unsicherheiten nach Typ B (nichtstatistische Methode). Zahlreiche durchgerechnete Beispiele geben konkrete Anleitungen und demonstrieren, wie die Ergebnisse ins Praktikumsprotokoll eingehen und wie sie diskutiert werden. Das vorliegende Kompendium ist sowohl fur Studierende in einem Bachelor- oder Lehramtsstudiengang Physik als auch fur Studierende in natur- und ingenieurwissenschaftlichen Studiengangen mit Nebenfach Physik geeignet.

Das vorliegende Lehrbuch bietet Studierenden der Natur- und Ingenieurswissenschaften einen ubersichtlichen und anschaulichen Einstieg in den Umgang mit Messdaten und deren Interpretation unter Verwendung der Messunsicherheit - fruher oft Fehlerrechnung genannt. Dabei stehen das Verstandnis und die Vermittlung von direkt anwendbarem Wissen im Vordergrund. Auf lange mathematische Herleitungen wird weitgehend verzichtet. Auf Basis einiger einfacher Grundprinzipien wie der Verteilung der Messwerte oder dem mathematischen Modell einer Messung fuhrt dieses Buch in zentrale Themen ein: - das Messen an sich, - die Angabe von Messergebnissen, - das Konzept der Unsicherheit, - die Auswertung von Messdaten mittels verschiedener Methoden, - sowie die Bewertung der erhaltenen Ergebnisse. Alle diese Themen werden anhand vielfaltiger Beispiele ausfuhrlich dargestellt und die Anwendung der abstrakten Konzepte anhand konkreter Zahlenbeispiele veranschaulicht. Fragen zur Selbstkontrolle sowie zur Vertiefung der Inhalte runden jedes Kapitel ab.

Das Buch beinhaltet die Ergebnisse des dreijahrigen Verbundprojekts Separator i4.0 des BMBF-Spitzenclusters it's OWL. Gegenstand des Projekts war die nachhaltige Einbindung von Expertenwissen in die zukunftsweisende Weiterentwicklung und Optimierung von Separationsprozessen. Durch die Entwicklung neuartiger intelligenter Komponenten aus dem Bereich der Sensorik wird es zukunftig moeglich sein, Separatoren und die zugehoerigen Prozesszusammenhange zu verstehen und diese oekologisch/oekonomisch optimal auszulegen und zu betreiben. Hierzu wurde ein Instrumentarium bestehend aus Methoden und Loesungen erarbeitet, das daruber hinaus auf analoge Problemstellungen komplexer maschinenbaulicher Anlagen anwendbar sein wird.

Dieser Band der Reihe Fachwissen Technische Akustik behandelt die in der Bauakustik meistverbreiteten Messmethoden, vom theoretischen Hintergrund uber anwendungspraktische Fragestellungen bis hin zu den nationalen und internationalen Normen. Die Normenreihe der DIN EN ISO 12354 dient dabei als roter Faden, da sie die messbaren Groessen der Bauakustik in einen Gesamtzusammenhang bringt. Ausgehend von den Aufgabenstellungen der bauakustischen Messtechnik werden die in Frage kommenden Kenngroessen erlautert. Ein wesentlicher Aspekt ist der Zusammenhang zu den bestehenden nationalen und internationalen Normen. Schwerpunktmassig werden die Grundprinzipien der Luft- und Trittschalldammung behandelt. Beschrieben werden Messverfahren, die im Labor und in Gebauden zum Einsatz kommen. Dabei wird ausfuhrlich auf die Schalldammung als Bauteil- bzw. Systemeigenschaft eingegangen. Die aus den physikalischen Grundlagen ableitbaren Voraussetzungen der Messverfahren wie z.B. die Anforderungen an die Schallfelder und die daraus ableitbaren Festlegungen der Messverfahren (z.B. Position und Anzahl von Lautsprechern und Mikrofonen) werden eingehend diskutiert. Auf praktische Fragestellungen wie die Notwendigkeit der Fremdgerauschkorrektur oder den Einfluss der Koerperschallnachhallzeiten auf die Messergebnisse wird bei den jeweiligen Messverfahren ebenfalls Bezug genommen. Ein ausfuhrliches Literatur- und Normenverzeichnis erganzt die behandelten Themen, so dass eine weiterfuhrende Vertiefung ermoeglicht wird.

In diesem Band der Reihe Fachwissen Technische Akustik werden Grundlagen der Abtastung und Quantisierung, digitale Filter sowie mehrere digitale Signalverarbeitungsmethoden beschrieben: Echtzeit-Frequenzanalysator, 2-Kanal-FFT-Analysator mit Sweep- oder Rauschanregung und Maximalfolgenmesstechnik. Anwendungen und Fehlerquellen der digitalen Messverfahren werden an Beispielen diskutiert.

Fur akustische Planungen ist es unerlasslich zu wissen, wie viel Schall eine Quelle abstrahlt. Auch die Wahl einer gerauscharmen Maschine ist nur moeglich, wenn die jeweiligen Herstellerangaben miteinander vergleichbar sind. Die Schallleistung ist in beiden Fallen die passende Groesse, da sie die Schallabstrahlung einer Quelle unabhangig vom umgebenden Raum beschreibt. Gerade diese Ortsunabhangigkeit ist aber erforderlich, um mehrere Quellen zuverlassig vergleichen zu koennen oder um z.B. die an einem Arbeitsplatz in einer Werkhalle oder an einem Immissionsort in der Nachbarschaft zu erwartenden Gerauschimmissionen prognostizieren zu koennen. In dem Band "Schallleistung" werden die theoretischen Grundlagen erlautert und verschiedene, grundlegende Messmethoden vorgestellt. Damit wird die Leserin oder der Leser in die Lage versetzt, das fur eine spezifische Messaufgabe passende Messverfahren auszuwahlen und, falls in den einschlagigen Regelwerken keine Vorgaben fur besondere Einzelfalle zu finden sind, angepasste Loesungen zu erarbeiten, die mit den jeweiligen Messprinzipien in Einklang stehen.

A multidisciplinary reference of engineering measurement tools, techniques, and applications--Volume 2

"When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of science." "-- Lord Kelvin"

Measurement falls at the heart of any engineering discipline and job function. Whether engineers are attempting to state requirements quantitatively and demonstrate compliance; to track progress and predict results; or to analyze costs and benefits, they must use the right tools and techniques to produce meaningful, useful data.
