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