Echo Signal Processing

This book presents introductory and advanced topics in the areas of signal theory and processing as specifically applied to acoustic echo-location. It is written at the senior undergraduate or graduate level and assumes some familiarity with signal processing subjects such as linear and complex algebra, probability, advanced calculus, and linear system theory. The material is presented as a logical development starting with the basic principles of signal theory and proceeds to the development of topics in detection and estimation theory, waveform design, echo modeling, scattering theory, and spatial processing. Echo Signal Processing addresses the practical as well as theoretical aspects of receiver and waveform design and should be of interest to the practicing engineer as well as the student. Numerous examples demonstrating the concepts are provided and important relationships are boxed. The book departs from many radar-oriented texts as the effects of relative motion are treated in terms of the dilation of the signal time base rather than as a simple Doppler frequency shift. The fundamental detection, estimation, time dilation, and waveform theory presented is of a general nature and applicable to communications and radar as well as sonar.
