GTD model-based time-shift invariant target identification using matching pursuits and likelihood ratio tests

  • Published:
Journal of Electronics (China)

Abstract

In order to improve the identification capability of ultra wide-band radar, this paper introduces a step-variant multiresolution approach for the time-shift parameter estimation. Subsequently, combining with the approach, a Geometrical Theory of Diffraction (GTD) model-based time-shift Invariant method to target identification using Matching Pursuits and Likelihood Ratio Test (IMPLRT) is developed. Simulation results using measured scattering signatures of two targets in an ultra wide-band chamber are presented contrasting the performance of the IMPLRT to the Wang’s MPLRT technique.
