Convoy tracking in Doppler blind zone regions using GMTI radar

In this paper, the problem of tracking convoys using Ground Moving Target Indicator (GMTI) radar systems is investigated. Some relevant techniques are reviewed. An approach to exploit group information, road map, and Doppler blindness information in convoy tracking is proposed. Simulated measurement data are used to evaluate the performance against a generic Global Nearest Neighbor (GNN) tracker using unscented Kalman filter (UKF). The results demonstrate improved tracker performance in terms of track continuity and estimation errors.
