%X To tackle the problem of tracking a maneuvering emitter by a single passive observer, an algorithm of combining the Central Difference Filter(CDF) and Interacting Multiple-Model(IMM) method is proposed. The proposed algorithm is easy to implement due to no request of calculating the Jacobian matrix, and more numerical stable by rebuilding traditional IMM algorithm into square root form. The proposed algorithm is applied to single observer passive location by using radial acceleration and angle information. Computer simulation results show that the presented method has similar performance to UT based IMM, and better performance than EKF based IMM in tracking accuracy.
