摘要

According the pre-research, the distribution of small and dim targets' edges make obvious difference to that of clouds that are the main interferences under cloud clutter. In this essay, the characteristics of multi-scale edges are used to locate the correlation coefficient, the small targets and noise are the category of Impulse-edge and background is the category of step-edge, and then the background is reconstructed the by the alternative projection algorithm directly. Finally, using the threshold to the result that is from the subtraction between reconstructed image and original image, the targets can be acquired. The experiments show that the method can get a lower false alarm rate in a low signal to noise ratio.
