Research of the aerial target ranging on single-station dual-band IR imaging system

In this paper the Staring Infrared Imaging System process is divided into two stages, the one is related with the target distance, another with the sensor only. The apparent radiance of the airborne target and the expression between the pixel gray and the apparent radiance were deduced based on each stage respectively. Then the aerial surface target distance was deduced based on the single-station dual-band infrared imaging system. Lastly the algorithm was validated by the IR images got from the aerodrome, and the results and ranging errors were analyzed.
