An Analysis of a Digital Correlation Technique for Multi-Sensor Terminal Guidance in an Air-to-Surface Missile
Abstract
A terminal guidance map-matching technique was evaluated on a digital computer. Imagery of known quality, from flights of the AN/APQ-97 radar and AN/ AAR-33 microwave radiometer, were correlated for targets of varying contrast levels. System performance, Characterized by a C.E.P. of 26 ft. excluding missile airframe steering and response errors, was obtained on targets having large areas with high contrast, such as bridges, airfields, and boatdocks. Examples of these target classes were studied at the lowest altitude guidance stage, which determines impact C.E.P. One bridge was studied at low, middle, and high altitudes to simulate major portions of the entire terminal sequence of repeated position fixing and course correction.
