Abstract
This paper addresses the issue of target detection in Gaussian noise for wideband radar systems. Through the use of the parsimonious singularity expansion method (SEM) representation of the late-time transient radar return and Bayesian detection theory, an aspect independent detection method based on a generalized likelihood ratio test (GLRT) is developed. The resulting decision rule has a non-central Χ2 distribution which is used to analyze the performance of the GLRT in terms of the probability of detection (PD) and the probability of false alarm (PF) . Results illustrating the performance of the GLRT for two different thin wire targets are displayed in the form of receiver operating characteristics. Simulation results are generated to verify the analytical receiver operating characteristics.
