Abstract
An automated E-pulse scheme for target discrimination was
initially presented by Ilavarasan et al. (1993) without an analytic
performance evaluation. Assuming that target responses are contaminated
with white Gaussian noise, an automated E-pulse scheme is rigorously
analyzed to yield a reliable measure of performance. The discrimination
performance of this automated E-pulse scheme is determined
quantitatively through the use of energy discrimination numbers (EDNs).
Statistics of the EDNs are evaluated analytically to derive the
probability of correct identification. The probability of identification
as a function of signal-to-noise ratio (SNR) is evaluated using the
theoretical scattering data for all potential targets to predict the
performance of the automated E-pulse scheme. These theoretical results
are corroborated by direct simulation of the discrimination scheme. In
addition, the probability density functions of the EDNs are presented
providing new physical insights into E-pulse performance as a function
of target geometries and SNR
