Sb. Park et al., MULTIPLE-TARGET ANGLE TRACKING ALGORITHM USING PREDICTED ANGLES, IEEE transactions on aerospace and electronic systems, 30(2), 1994, pp. 643-648
We modify a multiple target angle tracking algorithm presented by Swor
d, et al. The predicted estimates, instead of the existing estimates,
of the target angles are updated by the most recent output of the sens
or array to improve the tracking performance of the algorithm for cros
sing targets. Also, the least square solution is modified to avoid abn
ormally large angular innovations when the target angles are very clos
e. The improved performance of the proposed algorithm is demonstrated
by computer simulations.
