Simulation Analysis on Track Initiation of Multi-Model PDA Algorithm for Sky-wave OTHR

In OTHR target tracking,it is very difficult to initialize target tracks.In this paper,multi-model PDA is analylized in OTHR target automation track initiation via computer simulation.Simulation results show that multi-model PDA algorithm has good performance in OTHR track initiation.Besides this,the multi-model PDA shows strong robustness to Markov switch probability between visibility and invisibility of target and detection probability.
