Summary

Timed Perfectly to Coordinate With the Introduction of Array Processing into Commercial Applications ..Costs of array processing systems have recently undergone dramatic price decreases, which means they are beginning to make appearances in commercial buildings.Practical Array Processingprovides the knowledge needed for performing a full-systems engineering analysis on this type of system...This comprehensive guide provides a framework for designing these high-quality communication systems, including propagation effects, array calibration, and antenna array design. Readers will get a thorough but easy-to-follow tutorial on using algorithms to detect signals, estimating parameters of signals, and dealing with interference. Finally, this timely book shows how parameter estimates form multiple arrays can be combined to estimate the location of an emitter. Mathematical descriptions of algorithms are complemented with discussions of practical implementations in software or firmware. ..
