Discover the technology for the next generation of radar systems Here is the first book that brings together the key concepts essential for the application of Knowledge Based Systems (KBS) to radar detection, tracking, classification, and scheduling. The book highlights the latest advances in both KBS and radar signal and data processing, presenting a range of perspectives and innovative results that have set the stage for the next generation of adaptive radar systems. The book begins with a chapter introducing the concept of Knowledge Based (KB) radar. The remaining nine chapters focus on current developments and recent applications of KB concepts to specific radar functions. Among the key topics explored are: Fundamentals of relevant KB techniques KB solutions as they apply to the general radar problem KBS applications for the constant false-alarm rate processor KB control for space-time adaptive processing KB techniques applied to existing radar systems Integrated end-to-end radar signals Data processing with overarching KB control All chapters are self-contained, enabling readers to focus on those topics of greatest interest. Each one begins with introductory remarks, moves on to detailed discussions and analysis, and ends with a list of references. Throughout the presentation, the authors offer examples of how KBS works and how it can dramatically improve radar performance and capability. Moreover, the authors forecast the impact of KB technology on future systems, including important civilian, military, and homeland defense applications. With chapters contributed by leading international researchers and pioneers in the field, this text is recommended for both students and professionals in radar and sonar detection, tracking, and classification and radar resource management.

The book explains the concepts and theory of radar signal processing such as resolution, ambiguities, antennas, waveforms, the theory of detecting targets in noise and/or clutter, and tracking using data processing. It also presents equations for the determination of maximum radar range in free space and as affected by multipath and the horizon.
Following the pattern of the Internet growth in popularity, started in the early 1990s, the current unprecedented expansion of wireless technology promises to have an even greater effect on how people communicate and interact, with considerable socio-economic impact all over the world. The driving force behind this growth is the remarkable progress in component miniaturization, integration, and also devel- ments in waveforms, coding, and communication protocols. Besides established infrastructurebased wireless networks (cellular, WLAN, sat- lite) ad-hoc wireless networks emerge as a new platform for distributed applications and for personal communication in scenarios where deploying infrastructure is not feasible. In ad-hoc wireless networks, each node is capable of forwarding packets on behalf of other nodes, so that multi-hop paths provide end-to-end connectivity. The increased flexibility and mobility of ad-hoc wireless networks are favored for appli- tions in law enforcement, homeland defense and military. In a world where wireless networks become increasingly interoperable with each other and with the high-speed wired Internet, personal communication systems will transform into universal terminals with instant access to variate content and able of handle demanding tasks, such as multimedia and real-time video. With users roaming between networks, and with wide variation in wireless link quality even in a single domain, the communications terminal must continue to provide a level of Quality of Service that is acceptable to the user and conforms to a contracted Service Level Agreement.
Inventory and monitoring of coastal aquaculture and fisheries structures provide important baseline data for decision-making in planning and development, including regulatory laws, environmental protection and revenue collection. Mapping these structures can be performed with good accuracy and at regular intervals by satellite remote sensing, which allows observation of vast areas, often of difficult accessibility, at a fraction of cost of traditional surveys. This study is based on interpretation of satellite imaging radar data and a detailed image analysis procedure id described. The report aims at the necessary technology transfer for and operational use of the approach indicated in other similar environments.
Ein Startup ist nicht die Miniaturausgabe eines etablierten Unternehmens, sondern eine temporäre, flexible Organisation auf der Suche nach einem nachhaltigen Geschäftsmodell: Das ist die zentrale Erkenntnis, die dem "Handbuch für Startups" zugrundeliegt. Es verbindet den Lean-Ansatz, Prinzipien des Customer Development sowie Konzepte wie Design Thinking und (Rapid) Prototyping zu einem umfassenden Vorgehensmodell, mit dem sich aus Ideen und Innovationen tragfähige Geschäftsmodelle entwickeln lassen. Lean Startup & Customer Development: Der Lean-Ansatz für Startups basiert, im Unterschied zum klassischen Vorgehen, nicht auf einem starren Businessplan, der drei Jahre lang unverändert umzusetzen ist, sondern auf einem beweglichen Modell, das immer wieder angepasst wird. Sämtliche Bestandteile der Planung – von den Produkteigenschaften über die Zielgruppen bis hin zum Vertriebsmodell – werden als Hypothesen gesehen, die zu validieren bzw. zu falsifizieren sind. Erst nachdem sie im Austausch mit den potenziellen Kunden bestätigt wurden und nachhaltige Verkäufe möglich sind, verlässt das Startup seine Suchphase und widmet sich der Umsetzung und Skalierung seines Geschäftsmodells. Der große Vorteil: Fehlannahmen werden erheblich früher erkannt – nämlich zu einem Zeitpunkt, an dem man noch die Gelegenheit hat, Änderungen vorzunehmen. Damit erhöhen sich die Erfolgsaussichten beträchtlich. Für den Praxiseinsatz: Sämtliche Schritte werden in diesem Buch detailliert beschrieben und können anhand der zahlreichen Checklisten nachvollzogen werden. Damit ist das Handbuch ein wertvoller Begleiter und ein umfassendes Nachschlagewerk für Gründerinnen & Gründer. Von deutschen Experten begleitet: Die deutsche Ausgabe des international erfolgreichen Handbuchs entstand mit fachlicher Unterstützung von Prof. Dr. Nils Högsdal und Entrepreneur Daniel Bartel, die auch ein deutsches Vorwort sowie sieben Fallstudien aus dem deutschsprachigen Raum beisteuern.
This definitive volume covers state-of-the-art over-the-horizon radar systems, with emphasis on the practical application of advanced signal processing techniques.
Schon die erste Auflage des englischen Lehrbuchs 'Fundamentals of Photonics' zeichnete sich durch seine ausgewogene Mischung von Theorie und Praxis aus, und deckte in detaillierter Darstellung die grundlegenden Theorien des Lichts ab. Es umfasste sowohl die Themen Strahlenoptik, Wellenoptik, elektromagnetische Optik, Photonenoptik, sowie die Wechselwirkung von Licht und Materie, als auch die Theorie der optischen Eigenschaften von Halbleitern. Die Photonik-Technologie hat eine rasante Entwicklung genommen seit der Publikation der ersten Ausgabe von 'Fundamentals of Photonics' vor 15 Jahren. Die nun vorliegende Zweite Auflage des Marksteins auf dem Gebiet der Photonik trägt mit zwei neuen und zusätzlichen Kapiteln den neuesten technologischen Fortschritten Rechnung: Photonische Kristalle sowie Ultrakurzpuls-Optik. Zudem wurden alle Kapitel gründlich überarbeitet und viele Abschnitte hinzugefügt, so z.B. über Laguerre-Gauss Strahlen, die Sellmeier-Gleichung, Photonenkristall-Wellenleiter, photonische Kristallfasern, Mikrosphären-Resonatoren, Optische Kohärenz Tomographie, Bahndrehimpuls des Photons, Bohrsche Theorie, Raman-Verstärker, rauscharme Avalanche-Photodioden, Abstimmkurven und Dispersions-Management.
