The E‐pulse technique has been applied in the past to the early‐time component of an ultra‐wideband radar response. Though its availability has been validated by several scale‐model targets, as pointed out by Poter's research results, the Prony model used in the E‐pulse technique is mismatched with the true target‐scattering behavior. In this paper, according to Poter's GTD model, the type and location parameters of scattering centers are used as templates to identify targets. With parameter templates, a GTD model‐based approach to target identification for ultra‐wideband radar using matching pursuits and likelihood‐ratio test (for short MPLRT‐GTD) is developed. The simulation results using measured scattering signatures of two targets in an ultra‐wideband chamber are provided to contrast the performance of the MPLRT‐GTD to the LRT and Li's E‐pulse technique. © 2006 Wiley Periodicals, Inc.
