Paper Abstract

One may describe the effect of a radar or sonar target on an incoming signal as a filter which produces a scattered signal. Chaotic signals are very sensitive to the effect of filters, so a radar or sonar target imposes a unique signature on a scattered chaotic signal. In this paper we describe a method that uses the concept of phase space dimension to create a reference from a scattered chaotic signal. This reference becomes part of a library, and comparing an unknown scattered signal to this library can reveal which target caused a particular scattered signal. Because we are not imaging the target, this method can use signal with low range resolution.
