ABSTRACT:
Two systems are disclosed in which a pointer is directed towards a moving target over a predetermined time interval. Angular information is derived from the pointer during this time interval to generate signals indicative of the distance of the object from the pointer. During a second time interval, the pointer is automatically directed towards the moving object by use of the information derived during the first time interval.
