In this paper, we propose a direct sequence ultra wideband (DS-UWB) radar system which estimates a distance between the radar and an object with a short correlation processing time. Unlike conventional DS-UWB radar systems using multiple variable length pseudo noise (PN) sequences, the proposed radar employs a short-length PN sequence reducing the correlation processing time by virtue of correlation accumulation which averages out the noise in the correlator outputs. Numerical results show that the proposed DS-UWB radar estimates the distance with a shorter correlation processing time while providing a better estimation performance compared with the conventional DS-UWB radar systems.
