In this paper, we first classify the nonideal scattering centers to three kinds through analysis the assumption of ideal scattering centers model. They are dispersive scattering centers, glide scattering centers and anisotropic scattering centers.

• 通过概括理想点散射模型所包含的假设前提条件,限定出了模型失配的原因,提出了非理想散射中心的分类方法:把它们分为色散型散射中心、滑动型散射中心和各向异性散射中心,并分析了各种类型非理想散射中心在图像域的表征。
