摘要
Abstract
Scattering center is the essential electromagnetic scattering characteristic of the radar targets in high frequency region, which is of great importance for SAR imagery interpretation and target recognition. Compared with classical ideal point scattering center model, attributed scattering center model is more accurate in modeling the scattering characteristic of the high resolution SAR imagery targets. However, because of its high dimensionality, the method of attributed scatteVing center extraction is more complicated. This paper presents the region decoupled-approximate maximum likelihood-CLEAN(RD-AML-CLEAN) method for extracting scattering center in high resolution SAR imagery. The performance of the method is analyzed and evaluated qualitatively and quantitatively by simulating SAR imagery.关键词
