Abstract: A tracking system suitable for tracking a target from a command station includes a transponder on the target which transmits signals in response to signals received from a command control transmitter at the command station. The signals transmitted by the transponder are received by a receiver at the command station and a target range signal is developed in accordance with the time interval between the signal transmitted by the command control transmitter and that received by the receiver. The azimuth of the target is determined by means of a servo-control system which automatically locks the receiver antenna onto the target. Signals in accordance with target range and azimuth are processed in a position computer, the output of which is fed to an X-Y plotter which provides a continuous positional plot of the target.
