Abstract: A missile tracking system includes a target image sensor and a missile image sensor which record image data during respective target image exposure periods and missile image exposure periods. The missile is provided with an image enhancer such as a beacon or a corner reflector illuminated from the ground, which enhances the missile image only during the missile image exposure periods.

Abstract: Solid state imaging apparatus comprising a charge-coupled frame transfer image sensor including an image-sensitive integration region for forming a charge pattern representative of an incident image, first and second storage regions associated with respective opposed ends of said integration region, and charge transfer means for shifting the charge pattern formed in said integration region into a selected one of said storage regions.

Abstract: Rotating surveillance systems of the type which detect a moving object within a field-of-view and provide a representative image of the object may suffer from limited sensitivity when having a wide coverage. The system described herein detects and provides an identifiable image of a moving object within its field-of-view by forming an image of the object on a charge-coupled device and determining the rate of relative movement between the image and the device and hence using the rate of relative movement to provide signals which hold the image of the moving object substantially stationary with respect to the imaging sites of the charge-coupled device to produce a generally sharp image of the object compared with the background.
