From the reviews: "Echo Signal Processing is a book that is concerned primarily with echo location and sonar. ... will be of use to graduate students and lecturers teaching signal processing with special emphasis on echo-location detection and estimation. ... Echo Signal Processing progresses in a methodical way, explaining basic signal processing principles, kinematic formation of echoes, and the fundamentals of echo detection and estimation for simple point-scattering processes. Each chapter ends with an extensive bibliography of where the reader can learn more about a particular topic." (Dharmendra Lingaiah, IEEE Circuits & Devices Magazine, Vol. 21 (2), March/April, 2005)
