Research on Target Tracking Technology of OTHR based on MPDA

Considering the problem of OTHR´s target tracking, which estimates the state of a discrete-time, linear stochastic system whose observation process consists of a finite set of known, non-linear measurement models. MPDA (multipath probabilistic data association filter) is capable of exploiting multipath target signatures arising from discrete propagation modes that are resolvable by the radar. In this paper, numerical simulations are made under zero-clutter environment in planar measurement model and spherical measurement model of OTHR respectively. When tracking a single, non-maneuvering target in an environment where up to four possible measurements of state are received, the simulation results show that the performance under spherical model is superior to that under planar model
