摘要： An antitank weapon system is shown to include a projectile carrying at least one pulsed laser radar which periodically illuminates swaths of the underlying terrain, means for processing return signals to distinguish between the radar signatures of objects on such terrain and means for firing submunitions to impact on any object whose radar signature corresponds to that of a tank or other desired target.

摘要： An automatic focusing system for a camera apparatus utilizes a two-dimensional photosensitive array to determine image sharpness as a function of the image information sensed in both the rows and columns of individual photosensitive pixel elements. A transfer function may be imposed upon the electronic information signal derived from the two-dimensional photoresponsive array or, alternatively, upon the incident scene light to the two-dimensional photoresponsive array to centerweight the focus condition determining signal where the principle subject will be most likely framed.
