A DS-UWB radar with a correlation accumulating distance estimator

This paper proposes a novel direct sequence ultra wideband (DS-UWB) radar system with a reduced correlation processing time. The distance estimator in the proposed DS-UWB radar accumulates the correlator outputs to average out the noise, and thus, reduces the correlation processing time by shortening the required length of the DS-UWB signal. Numerical results confirm that the proposed DS-UWB radar estimates a distance with a reduced correlation processing time while providing a better estimation performance compared with the conventional DS-UWB radar systems with a distance estimator exploiting the correlations individually.
