Description

Radar, Sonar, and Holography: An Introduction provides an introduction to the technology of radar and sonar. Because the new science of holography is affecting both these fields quite strongly, the book includes an explanation of the fundamental principles underlying this new art (including the subjects of wave coherence, interference, and diffraction) and of the hologram process itself. Finally, numerous examples are discussed which show how holography is providing new horizons to radar and sonar systems.
The book thus also provides a simple approach to the new technology of holography. The discussions clarify the basic difference that exist between photography and holography, on the one hand, and between standard sonar and radar, on the other; and the hologram versions of these two technologies.
The book should be useful as a supplementary reading assignment to early college students in science and engineering, and also to senior high students having a bent for science and engineering.
