Research on Multi-mode Fusion Tracking of OTHR Based on Auction Algorithm

In OTHR´s tracking system, we will estimate the state of a discrete-time, linear stochastic system whose observation process consists of a finite set of known, non-linear measurement models. MPDA is capable of exploiting multipath target signatures arising from discrete propagation modes that are resolvable by the radar, but it is very time-consuming and will bring multipath tracks. In this paper, a multi-mode fusion tracking of OTHR based on auction algorithm (A-MFT) is proposed, which effectively solve the problem of multi-mode measurements. When tracking a single and non-maneuvering target with four possible measurements, simulations in clutter environment show that the computing speed of the algorithm proposed in this paper is greatly higher than that of MPDA, and the tracking precision just a little lower than that of MPDA, further more, A-MFT will not bring multipath tracks and do not need consequent track association.
