Simple OFDM-based MIMO radar for real-time short-range area surveillance

This paper presents a simple OFDM-based MIMO radar for real-time area surveillance applications. The radar is able to estimate range, velocity and azimuthal positions of multiple objects simultaneously within one transmit cycle. Detection, clustering, data association and tracking are then performed to estimate the number of targets, extract the target trajectories and improve the positioning accuracy. The radar processing and algorithms have been chosen so that a real-time implementation is feasible, while providing a satisfactory performance. The performance of the radar system is evaluated by numerical simulations for an automotive scenario with multiple targets.
