engineers and sonar engineers. This book is a reprint of the second edition published in 1991 and is still a classic text in the field. Updated and expanded in 1991, this edition contains all the valuable information in the earlier edition plus a detailed discussion of adaptive processing as applied to spatial filtering. You will also find review sections on Fourier analysis, correlation, random processes and hypothesis testing. Highlights include: generation and propagation of compressional acoustic waves in the ocean; narrow band signatures of surface ships caused by cavitating propeller blades and diesel engine firing; optimization of signal-to-noise ratio and spatial resolution in the presence of multiple signals; ambient noise in the ocean; and examples of system performance.
