Focal Plane Array

" Once again, Harry Van Trees has written the definitive textbook and research reference." – Norman L. Owsley Office of Naval Research, IPA University of Rhode Island A comprehensive treatment of optimum array processing Array processing plays an important role in many diverse application areas, including radar, sonar, communications, seismology, radio astronomy, tomography, and cellular communications. Optimum Array Processing gives an integrated presentation of classical and statistical array processing. Classical analysis and synthesis techniques for linear and planar arrays are developed. A statistical characterization of space-time random processes is provided. Many different aspects of optimum array processing are covered, including waveform estimation, adaptive beamforming, parameter estimation, and signal detection. Both plane-wave signals and spatially spread signals are studied, and all results are developed in a pedagogically sound manner. This book provides a fundamental understanding of array processing that is ample preparation for research or implementation of actual array processing systems. It provides a comprehensive synthesis of the array processing literature and includes more than 2,000 references. Readers will find an extensive variety of models and criteria for study and comparison, realistic examples and practical applications of optimum algorithms, challenging problems that expand the book’ s material, and detailed derivations of important results. A supplemental Web site is available that contains MATLAB® scripts for most of the figures used in the book so readers can explore diverse scenarios. The book uses results fromParts I and III of Detection, Estimation, and Modulation Theory. These two books have been reprinted in paperback for availability.

AN AUTHORITATIIVE, UP-TO-DATE INTRODUCTION TO PHYSICAL ACOUSTICS Easy to read and understand, Fundamentals of Physical Acoustics fills a long-standing need for an acoustics text that challenges but does not overpower graduate students in engineering and physics. Mathematical results and physical explanations go hand in hand, and a unique feature of the book is the balance it strikes between time-domain and frequency-domain presentations. Fundamentals of Physical Acoustics is intended for a two-semester, first-year graduate course, but is also suitable for advanced undergraduates. Emphasis on plane waves in the first part of the book keeps the mathematics simple yet accommodates a broad range of topics: propagation, reflection and transmission, normal modes and simple waveguides for rectilinear geometries, horns, inhomogeneous media, and sound absorption and dispersion. The second part of the book is devoted to a more rigorous development of the wave equation, spherical and cylindrical waves (including the more advanced mathematics required), advanced waveguides, baffled piston radiation, diffraction (treated in the time domain), and arrays. Applications and examples are drawn from: Atmospheric acousticsNoise controlUnderwater acousticsEngineering acousticsAcoustical measurements Supplemented with more than 300 graphs and figures as well as copious end-of-chapter problems, Fundamentals of Physical Acoustics is also an excellent professional reference for engineers and scientists.

Focal plane shutter - In camera design, a focal plane shutter is so-called because it is right in front of the focal (film) plane of the camera. The main advantages of the focal plane shutter is that the interchangeable lenses do not each need to have a central shutter built into them, and quite fast effective shutter speeds are possible.

Focal plane - The focal plane of a lens is a plane that is perpendicular to the axis of the lens and passes through its focus.

Planar array radar - The planar array radar uses a high-gain planar array antenna. A fixed delay is established between horizontal arrays in the elevation plane.

Plane partition - In mathematics, a plane partition is a two-dimensional array of nonnegative integers n_{i,j} which are nonincreasing from left to right and top to bottom:
