Book Description
3rd Generation FLIR (3rd Gen) is defined as a dual band (MWIR and LWIR) thermal imager. It is targeted to be one of the principle sensor systems for the Army's Future Combat System (FCS), Stryker, and Airborne Reconnaissance System. In early 2005, the Night Vision and Electronic Sensors Directorate (NVESD) created a large scale project to research and quantify the potential benefits of a 3rd Gen FLIR. This research was partitioned up into multiple individual studies, each of which is focused on a particular technical area, i.e., topic, to quantify its impact on the performance of a 3rd Gen FLIR. The set of topics include long range target identification (ID), aided target recognition (AiTR), apparent high temperature (T) sources of clutter, target and background contrasts and signatures, conventional and urban search and detection, advanced signal processing, cold weather, atmospheric turbulence, sensor integration time, camouflage, spectral signature differences, smoke, pilotage, wet targets, laser susceptibility, and path radiance. Whenever possible and appropriate, actual MWIR and LWIR imagery were used as inputs in the applicable physics (or psycho-physics) models. Even though every attempt was made to partition a research project of this size and scope into individual, independent components of an n-dimensional parameter space, it was obvious that there were varying degrees of dependence amongst and between these topics. In each of these studies, specific benefit of 3rd Gen FLIR was assessed from either the direct or indirect impact upon target discrimination task performance.

Book Description
This comprehensive reference details the principles and components of the Linear Shift-Invariant (LSI) infrared and electro-optical systems and shows you how to combine this approach with calculus and domain transformations to achieve a successful imaging system analysis. Ultimately, the steps described in this book lead to results in quantitative characterizations of performance metrics such as modulation transfer functions, minimum resolvable temperature difference, minimum resolvable contrast, and probability of object discrimination. The book includes an introduction to two-dimensional functions and mathematics which can be used to describe image transfer characteristics and imaging system components. You also learn diffraction concepts of coherent and incoherent imaging systems which show you the fundamental limits of their performance. By using the evaluation procedures contained in this desktop reference, you become capable of predicting both sensor test and field performance and quantifying the effects of component variations.

Book Description
This newly revised and updated edition offers a current and complete introduction to the analysis and design of Electro-Optical (EO) imaging systems. The Third Edition provides numerous updates and several new chapters including those covering Pilotage, Infrared Search and Track, and Simplified Target Acquisition Model. The principles and components of the Linear Shift-Invariant (LSI) infrared and electro-optical systems are detailed in full and help you to combine this approach with calculus and domain transformations to achieve a successful imaging system analysis. Ultimately, the steps described in this book lead to results in quantitative characterizations of performance metrics such as modulation transfer functions, minimum resolvable temperature difference, minimum resolvable contrast, and probability of object discrimination. The book includes an introduction to two-dimensional functions and mathematics which can be used to describe image transfer characteristics and imaging system components. You also learn diffraction concepts of coherent and incoherent imaging systems which show you the fundamental limits of their performance. By using the evaluation procedures contained in this desktop reference, you become capable of predicting both sensor test and field performance and quantifying the effects of component variations. The book contains over 800 time-saving equations and includes numerous analyses and designs throughout. It also includes a reference link to special website prepared by the authors that augments the book in the classroom and serves as an additional resource for practicing engineers. With its comprehensive coverage and practical approach, this is a strong resource for engineers needing a bench reference for sensor and basic scenario performance calculations. Numerous analyses and designs are given throughout the text. It is also an excellent text for upper-level students with an interest in electronic imaging systems.
