概要

• 論文の詳細を見る

• This study proposes a high-resolution UWB (Ultra Wide-Band) Doppler radar imaging algorithm with a small number of antennas. Targets are resolved first in terms of range directions using smoothed pseudo Wigner distribution, and then in terms of angular directions with interferometry. Performance evaluation with numerical simulations and experiments shows the proposed algorithm achieves high-resolution imaging for multiple moving targets. The mean error of the estimated image is 5.2 mm, which corresponds to 1/58 of the nominal resolution determined by the bandwidth.
