Digital or optical processors are used to analyze images such as ultrasonic or x-ray signals to extract information. Theory of Remote Image Formation presents the mathematical models that form the basis of the algorithms required in such processing. Targeted to practitioners in industry and graduate students of electrical engineering and computer science, the 553-page volume covers such areas as tomography, the ambiguity function, transform and filter theory, base-band surveillance systems, two- and three-dimensional Fourier transform theory, image construction and reconstruction, and passive systems, where the signal source might be a galaxy or an earthquake. Data combination and tracking, and phase noise and distortion also are addressed. Richard E. Blahut; Cambridge University Press, Cambridge, UK, 2004; $110.
