New technique in single observer passive tracking based on Jerk Model

In this paper, we propose a new tracking filter for the highly non-linear Single Observer Passive Location And Tracking (SOPLAT) system based on the observation of bearing, bearing rate and difference time of arrival of emitter. The new method uses the Jerk model for the maneuvering target, and then uses the UKF to keep the tracking of the emitter. By using this method, the precision of the tracking filter can be improved, and it’s also good to the filter’s stability. The simulations proved the feasibility and availability of the new filter. At last, we also discuss the further research directions of the Jerk-UKF.
