Abstract

This paper analyzed the resolution of ultra wideband (UWB) ranging/imaging system based on the parameter estimation theory. The structure and features of DS-UWB were presented, which was advised to be applied for ranging/imaging. The evaluation algorithms of Cramer-Rao inequality and Fisher information in parameter estimation were introduced. The Cramer-Rao lower bound formula of UWB ranging/imaging system resolution was developed. The simulation results show that the decrease of the impulse duration time and the increase of the SNR help improve the resolution, which gives a theoretical explanation why the impulse has high resolution.
