Abstract
A switching method for measuring or tracking two neighboring flying targets in succession by means of a measuring installation having a television system. A regulation system receives course signals, which correspond to the deviation of the image of a flying target or object from the image center, and aligns the line of sight of the television camera at the flying target. An electronic window limits the formation of the deviation signals to the contribution of the image point of the flying target located in the window. During measurement of the first flying target by means of first deviation signals and a first window there is produced about the image center a second window and second deviation signals which are delimited by the second window. The first deviation signals are added, by actuating a control handle or stick to additional signals, in order to shift the line of sight and thus bring the image of the second flying target into the image center. Thereafter the regulation system is switched into operative relationship with a control by the second deviation signals. The invention is used to eliminate the effects of alignment errors and transient phenomena upon switching the measurement from one flying target to another flying target.
