Paper Abstract

A panoramic scanner using Time Delay and Integration Charge Coupled Device (TDI-CCD) technology that is presently directed towards a submarine periscope mission scenario is discussed. The system utilizes a large format TDI device coupled with real-time video processing techniques, i.e., dark signature removal, response non-uniformity correction, on-chip exposure control and background subtraction. This data processing, in combination with a real-time, digital falling raster display, produces a man-machine system capable of detecting and recognizing target silhouettes against the horizon under starlight illumination. The background subtraction techniques also provide the capability for achieving low contrast image enhancement under daylight illumination conditions. System details and experimental performance data are presented.
