National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Introduction to Wideband Ambiguity Functions and Time-Scale Representations for Radar/Sonar Applications.

ADA268722

Publication Date	1993
Personal Author	Borden, B.
Page Count	35
Abstract	Recent advancements in the ability of radar/sonar systems to launch and analyze signals of very short time duration have caused many to re-examine the so-called wideband ambiguity function. Much of this work has been at a mathematical level that has placed it out of reach to many radar and sonar engineers. Some of the work has been incomplete--occasionally even incorrect. Our present pedagogical discussion uses the standard time-frequency motivation for time-scale distributions. We compare and contrast the usual narrowband techniques with the wideband approach and explain how high-resolution downrange imaging requires an understanding of the latter. Ambiguity function, Wideband, Wavelet.
Keywords	Radar Sonar High resolution Narrowband Resolution Ambiguity functions Wavelets
