Paper Abstract

Air defense and anti-missile operation usually demands the EO device to quickly detect the sea-skimming missile in a given area. Because the small sea-skimming target usually features low brightness, small size and susceptible to interference from the sea horizon and sea surface clutter. Therefore, a quick search and threat evaluation algorithm is proposed against sea-skimming small targets. First, statistic row mean value and gradient are worked out, and the sea horizon is fitted by means of least square criterion. The background shall be suppressed by using morphological factor and the image shall be binarized by using self-adaptive threshold. Finally, statistic suspicious target features are carried out for threat evaluation of these suspicious targets, sea clutter and sea horizon interference are eliminated and the high priority threat is picked up.
