The analysis of an airborne line-scan surveillance system based on a linear-array solid state sensor mounted parallel to the longitudinal axis of the aircraft with a scanning mirror providing cross-track area coverage, resulted in a simple kinematic model which can be useful in the systematic design of such systems. Practical implementation of the model using state of the art technology was considered prior to the actual design and construction of a laboratory prototype and simulation system. Experimental evaluation of the system confirmed that a digital data rate of 4-8 Mbit per second is feasible for acquisition and real-time display of visual information at a ground area coverage rate of almost 200 km2/hr for relative flight altitude of 3000 ft and velocity of 80 knots, attaining a ground pixel size of 0.25 m. A digital image processing facility was interfaced to the system providing offline processing capabilities for selected image-frames. Online analog and digital processing was performed to provide compensation for errors due to image motion and aircraft attitude, as well as acquisition errors due to uneven illumination. Restoration of some geometrical distortions was also performed.
