Abstract
An analog terminal guidance system and device. One dimensional strips of a arget scene are stored in a line in a longitudinally extending acousto-optic device as index of refraction variation pattern signals. Real time signals corresponding to the scene actually being viewed by the vehicle are propagated across the stored signals, and the results of an acousto-optic correlation are utilized to determine X and Y error. Scale error is compensated for by changing the data rate of the real time signals, and 21/2 and 3D schemes improve the accuracy of the correlation.
