点散射 meaning in Chinese
point scattering
Examples
- The mett cross section applies to a point scatterer .
莫脱截面适用于点散射体。 - According to the concept and basic form of svpsf , the cavity and duct scattering is examined , and a method is developed to remove the duct - induce dispersion effect
推演了典型非点散射结构?腔体结构的二维svpdf的具体形式，得到消除其散焦效应的积分变换域滤波方法。 - The method is demonstrated by using real data of airplane . the airplane isar image is evidently enhanced , and the physics - based feartures of scattering centers is gained by the method
依此框架完成了对飞机目标isar图像有效的增强处理，提取到了反映成像目标结构特征的点散射中心集合。 - On the other hand , in image domain , spatially varying point - spread function ( svpsf ) is defined to demonstrate how the effects of complex scattering centers which cause scattering model mismatch can be interpreted as being due to a svpsf acting on a ideal scatterer
同时在图像域引入二维空变点展布函数( svpdf )来解析表达非点散射机制对理想“点”的展布作用。 - 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 . also we conclude that all of them make the image blur by research on their display on imaging
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。
