摘要:
This letter discusses the ability to improve the resolution of range and azimuth angle measurements by an interferometric localization system used to locate beacons within its line of sight (LoS) by exploiting stepped frequency signals impulse radio-ultra wideband (UWB) centered on two frequencies. This improvement does not require increasing the frequency bandwidth used. This solution uses a phase correlation method, usually applied to continuous wave signals, adapted to UWB pulse signals. The results obtained are compared with those computed by a classical method of energy detection by exploiting the same frequency band.
