Abstract: A system for recognizing and tracking a target with the use of an observation device which is directed toward the target and which follows the target with the aid of a setting drive connected in series with a computer. The observation device furnishes a signal representative of the structure of the target to the computer for computation of the genuine correlation between a stored target structure signal B(x) which corresponds to the previously received image of the scene under observation, and the shifted target structure signal B' (x-.xi.) which corresponds to the momentary image of the scene under observation, the genuine target deviation being expressed by the position of the maximum of the cross-correlation functionK (.xi.)=.intg.B (x) B' (x-.xi.) dxThe computer continuously determines the deviation of the target in the x direction and in the y direction from the center of the scene image and emits setting signals, which correspond to the deviation, to the setting drive.

Abstract: Apparatus for enhancing incomplete, limited bandwidth, sequential signals generated by an image sensor. Each of the incomplete signals comprises a plurality of alternate lines containing information, the lines interposed therebetween being blanked. A picture display device is also provided, and an intermediate storage device interposed between the image sensor and the display device. The storage device stores a first of the incomplete image signals and combines it with the next sequential image signal to form a complete image signal. The complete image sgnal, which is displayed on the display device, contains the information in the next incomplete image signal on alternate lines, the lines therebetween containing the information in the first incomplete image signal. The invention also constitutes a method for enhancing incomplete limited bandwidth sequential signals wherein a first of these signals is stored and then combined with the next sequential image signal to form the complete image signal.
