Abstract
The performances of the Viterbi and the Interacting Multiple Model algorithms, applied to radar
tracking and detection, are investigated and compared. Two different cases are considered. In the
first case, targets acceleration is identical to one of the system models while in the second case it is
not. The algorithms performance depends monotonically on the maximal magnitude of the difference
between models acceleration, on the time interval between measurements and on the reciprocal of the
measurements error standard deviation. In general, when these parameters are relatively large, both
algorithms perform well. When they are relatively small, the Viterbi algorithm is better. However,
during delay periods, namely right after the start of a maneuver, the Interacting Multiple Model algorithm
provides better estimations.
