INVENTOR: HEINZ PICCOLRUAZ INVENTION: TARGET TRACKING SYSTEM ABSTRACT OF THE DISCLOSURE The target tracking system has high tracking reliability at small servo load and comprises a plural number of groups of target sensors having tracking signal travelling times which vary from one group to the other and defining respective lines of sight, a servo system causing the lines of sight to track the target, a target estimator for estimating the movement of the target, a servo estimator for estimating the movement of the servo system, and a regulator which identically controls the servo system and the servo estimator such that the vectorial difference between the estimate of the target movement and the estimate of the servo movement is caused to approach zero. During the target tracking operation, vectorial target deviation signals which are generated by groups of angle sensors, are processed by multipliers using respective matrices in order to produce related combined target deviation signals. The thus processed vectorial target deviation signals are directly applied to the servo system and the servo estimator in a manner as if there would be present only one respective angle sensor producing the combined target deviation signal.
