Multiple-input-multiple-output (MIMO) radars are widely used for target localization in many different fields such as airborne, remote-sensing, and autonomous driving systems. Recently, they are also becoming popular in indoor environments for human target tracking and activity recognition. For both automotive and indoor MIMO radar, the complex urban/indoor environment leads to multipath reflections from static objects such as buildings and walls. The detections from the multipath are called ‘ghosts’, which generate objects in the radar detection list that, in fact, do not exist. In the state-of-the-art, the problem of removing multipath ghosts in MIMO radars remains unsolved. Even though there have been some solutions based on prior knowledge of the reflector position (geometry model), which are called ray-tracing techniques, to analyze or eliminate multipath, it is not a realistic assumption that this multipath geometry information is known a priori.
The goal of this master thesis is to develop algorithms to track targets with a MIMO radar in a multipath environment and jointly estimate the multipath reflectors (e.g. wall position and room boundary). In the previous research of our team, we have proposed algorithms to recognize multipath without prior knowledge of multipath geometry in an indoor environment. The master project will be based on the model and measurements that have already been achieved completed.
