Abstract :
A cooperative spatial filtering method is presented to detect small targets around horizontal region for infrared search and track (IRST). Double window filter (DWF) can enhance signal-to-noise ratio then directional background removal filter (DBRF) can subtract horizontal background structure. Experimental results present upgraded detection rate and false alarm rate.
