With spherical coordinate, the adaptive estimation using multiple model filtering is
enhanced in this paper. The enhancement is achieved by using just two depended parallel
Kalman filters, instead of multiple models, with the probabilistically weighted average,
which provides the adaptive mechanism. The first filter is constant velocity filter (CVF)
which is used to estimate the position and velocity of the moving target in non maneuvering
course. The second filter calculates the acceleration and the new adjustment for the CVF.
The second filter is referred as variable velocity filter (VVF). Monte Carlo computer
simulation results are included to demonstrate the effectiveness of the proposed algorithm in
enhancement the multiple model adaptive filtering.
