Bearings only versus bearings and extent tracking for missile guidance systems utilising particle methods
This paper addresses the problem of bearings only and bearings and extent tracking for closed loop missile guidance systems using particle methods compared with derivative free methods. Lack of observability is a typical phenomenon for the bearings only tracking problem. We demonstrate that exploiting angular extent information does help mitigating the lack of observability issues. The simulation results show that the particle filter ourperforms the derivative free algorithms.
