Yh. Park et al., TRACKING USING THE VARIABLE-DIMENSION FILTER WITH INPUT ESTIMATION, IEEE transactions on aerospace and electronic systems, 31(1), 1995, pp. 399-408
An improved method for tracking a maneuvering target is proposed. The
proposed tracking filter is constructed by combining the recursive for
mulation of the input estimation approach with the variable-dimension
filtering approach. In the proposed approach, the filter also provides
the estimate of time instant at which a target starts to maneuver, wh
en a target maneuver is detected. Using this estimated starting time o
f the maneuver, the maneuver input is also estimated and the tracking
system changes to the maneuvering model. The computational load of the
proposed procedure is comparable to that of the input estimation appr
oach. Simulations are performed to demonstrate the efficiency of the p
roposed tracking filter, and comparisons with the interacting multiple
model (IMM) filter, the input estimation filter and the variable-dime
nsion filter are made.
