Abstract�� In the presence of standoff jamming(SOJ), radar has low probability of target detection, which brings up the trackloss and decreases the track lifetime. Aimed at these problems, a combined target tracking approach was presented. The approach has two components: particle filter based track before detect(PF-TBD) and adaptive detection threshold selection in multiple hypothesis tracking(MHT). Track management in different region was also considered. Simulation results indicate that the approach presented takes fully advantage of TBD, meanwhile the time efficiency spent in target tracking in the whole surveillance region is considered, and it has expanded 20% of the surveillance region of radar. The resulting advantage suggests that this approach is of important reference significance for the theory and realization of tracking system in the presence of SOJ or other jamming.
Keywords�� standoff jamming   particle filter based track before detect   multiple hypothesis tracking   surveillance region partitioning
