This text covers smart antenna technology, from the fundamentals to the latest developments, including new adaptive techniques developed by the authors. Sarkar (electrical and computer engineering, Syracuse U.) and co-authors provide 12 chapters covering topics including the difference between adaptive antennas and adaptive signal processing, adaptive processing using directive elements in a conformal array, multistage analysis, and a survey of models for radio wave propagation in rural and urban areas. The book provides a reference for engineers working on improvement of adaptive techniques, characterization of propagation channels, and applications of airborne phased arrays.
