Abstract :
A high resolution ultra wideband (UWB) positioning radar system based on time difference of arrival (TDOA) has been developed. The UWB radar system provides millimeter accuracy in dense multipath indoor environments for 1D, 2D, and 3D localization. The system is fully compliant with the FCC UWB regulations and utilizes time domain measurements to suppress both multipath signals and non-line of sight (NLOS) errors and has a potential for even sub-mm accuracy
