An investigation of the SFIMM algorithm for tracking manoeuvring targets

The paper discusses a selected filter interacting multiple model (SFIMM) algorithm for tracking a target manoeuvring in the X-Y plane. The SFIMM algorithm is a modified IMM algorithm which uses a subset of filters with the specific subset chosen by decision rules. Particular attention is focussed on the design parameters of the SFIMM algorithm, namely the subset type and the decision rule. The simulation results show that a considerable improvement in computation efficiency can be obtained with an SFIMM algorithm compared with a standard IMM algorithm with little degradation in tracking performance.<>
