Research on the Modified Shifted Rayleigh Mixture Filter and Its Use on Bearings-Only Maneuvering Target Tracking

The modified shifted Rayleigh mixture filter is introduced for bearings-only maneuvering targets tracking,which use Gaussian mixture reduction method based on cost-function to improve the shifted Rayleigh mixture filter.The MSRMF is based on jump Markov linear system and it permits the presence of strong noise. Simulations demonstrate the effectiveness of the MSRMF in challenging scenario with strong noise. It achieves the accuracy of a PF,while reducing the computational burden by an order of magnitude. Furthermore,it improves the SRMF as regards accuracy,through its computational demands is just about the same as the SRMF's.
