Abstract

Performance bounds on the estimates of position, intensity and geometry parameter of scattering centers based on wideband radar measurements are presented in analytic forms. The resolution limit for wideband radar and the SNR threshold for identifying scatterer´s geometry are further deduced. Though the results are obtained from the Cramer-Rao bound (CRB) matrix for damped exponentials (DE) after simplification, their validity and adaptability for geometric theory of diffraction (GTD) based scattering data have been verified by simulations
