Abstract
A correlation processor arrangement is used to guide an airborne vehicle along a path precisely to a predetermined destination. Guidance is divided into three distinct phases, and during each phase the position of the vehicle is verified by matching the view of its surroundings with stored reference data representing the expected fields of view. During the first navigation phase the stored data consists of predetermined terrain areas. During the second detection phase the destination is acquired, and during the third homing phase the view of the approaching destination is used as the stored reference data.
