| Popis: | For tracking multiple moving targets, a multi-radar system employing ultra-wideband millimeter-wave array antennas is introduced. To separate the multiple echoes and the different Doppler velocities of the targets, the frequency-domain interferometric technique is used and is followed by an interferometric imaging process. The system consists of multiple radar modules that are well-separated, allowing measurements of the Doppler velocities from different lines of sight. Thus, in addition to constructing high-resolution images, the multi-radar system is able to estimate the velocity vector of each target, which has been demonstrated in practice through measurements. |
