Abstract:
This paper describes a practical design of a precision TV tracking system, which, with
tracking error of only a few arc seconds, is stable and reliable in the field trial-operation.
The combined man-attendant aquisition system is first presented and the design criterion
of the tracker has been established. This namely criterion △≤15 %, should be maintained
so as to avoid the liability of missing the target.
In the second part of this paper emphasis is placed on the application of the third order
astatic method in the designing of such tracking system--using Z transform technique for
solving the problem and providing the optimum conditions.
σmax/ Ki=0 and 2σmax/ K >0
