Abstract
This paper presents a joint direction-of-departure (DOD) and direction-of-arrival (DOA) estimation in an ultra-wideband (UWB) multiple-input multiple-output (MIMO) radar system. The idea is to utilize multiple sinusoidal waves swept over the UWB bandwidth. A two-dimensional MUSIC algorithm was adopted to estimate the respective DOD and DOA at each frequency component. Histograms of the estimated angles were formulated to obtain the peak DOD and DOA. Simulation results demonstrated that the combination of the 2D-MUSIC and the angle histograms resulted in precise estimation of DOD and DOA. Indoor experiments also validated the proposed technique.
