ABSTRACT:
This system observes and registers the instantaneous position of a moving, distant object. A television camera receives an image on its sensitive surface, and direction of the object is registered continuously in a data processing unit. The range of the object is measured by transmitting two spaced, high frequency radiations to the object, on which is mounted a radio frequency transmitter to be actuated by the transmitted radiations, to transmit return radiations, which are compared with the original transmissions to measure the distance of the object and register the distance in the data processing unit. The data processing unit registers the direction and distance of the object.
