A device for the passive friend-or-foe discrimination of targets, comprising:video camera means defining an optical axis and providing video signals representative of an image of a target to be identified,mounting means for mounting said video camera means for rotation

[ What is claimed is:] [1.]1. A device for the passive friend-or-foe discrimination of targets, comprising:video camera means defining an optical axis and providing video signals representative of an image of a target to be identified,mounting means for mounting said video camera means for rotation about two axes,means exposed to radiation from said target and generating position signals indicative of the position of said target in a field of view,receiving means for receiving said position signals and generating therefrom follow-up signals,servo means connected to said mounting means and receiving said follow-up signals,said servo means responding to said follow-up signals by rotating said mounting means and thereby said video camera means about said two axes and thereby aligning said optical axis defined by said video camera means with said target;said image processing means connected to said video camera means and receiving said video signals representative of said image of said target; andsaid image processing means evaluating said video signals to identify said target as a friendly or enemy target.
