| Abstract: | A new method of IR small dim target detection based on big clutter background was provided. It worked well in heavy cloud and big moving clutter background. After analyzing the characters of big clutter background IR images, a new method was provided to detect the target using rectangle structure cell to eliminate noise based on morphological filter operator. Then, the later image was processed by doubled gated filter. The experiments process real data, and the results meet well and easy to realize by hardware. |
| Keywords: | Rectangle structure cell Morphological filter Double gated filter Recursive threshold |
