An interacting multiple model with constant filtering gain (CFG-IMM) algorithm is developed for target tracking which uses /spl alpha/-/spl beta/ and /spl alpha/-/spl beta/-/spl gamma/ filters as a means for mapping the different kinetic modes. Four methods which combine IMM with /spl alpha/-/spl beta/ and /spl alpha/-/spl beta/-/spl gamma/ filters at the interacting level are proposed. The simulation results show that this algorithm is not only highly accurate but also computationally efficient and robust in spite of the manoeuvring level and measurement noise level.
