Automatic reprogramming means for countermeasures system

摘要

A countermeasures system technique for destroying threat radar frame of reference. Automatic change of false target pattern is accomplished by any one of three different switching schemes or by any combination of them. The switching schemes comprehend (a) changing polarity of digital counts delivered to system range position program matrix inputs; (b) alternately enabling and disabling selected outputs of the range position program matrix, and (c) interchanging selected input gates of the system angle position program matrix.
