Abstract:

To overcome the strongly nonlinear and weak observable problems existing in singleplatform bearingsonly maneuvering target tracking, the multi-platform bearings only maneuvering target tracking algorithms are studied in this paper. A centralized shifted Rayleigh filter (CSRF) is proposed to apply to multi-platform bearings-only target tracking; further an interacting multiple model centralized shifted Rayleigh filter (IMMCSRF) is proposed and derived to track a maneuvering target. The simulation results show that this method has a high tracking accuracy and good stability and has very powerful practical application value.
