Analysis of Attribute Scattering Center Based on Image Domain

Attribute scattering center model provides a richer physical description of target scattering at high frequencies.The frequency and aspect dependence in the model is an important feature for target recognition.But the parameters have to be extracted in image domain because of complexity of model function,and image segmentation is a key step in the process.It needs a profound understanding of the representation of scattering center in image domain.On the basis of previous literature,we analytically transform the scattering model from the frequency-aspect domain into the image domain.The distribution characteristics of scattering center in image domain are analyzed fully,which serve a useful guidance for the partition of image and extraction of feature parameters.
