( 7 ) the experiment of the hot - image from phase scatterer in n31 nd - glass is carried out . the experimental results are found to be in good agreement with previous analytical and numerical results ( 7 )开展了n31钕玻璃介质中位相型衍射物形成热像规律的实验研究,得到了热像的位置、强度及像平面的能流分布等结果,结论与理论模拟结果吻合较好。
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。
Polarimetric synthetic aperture radar ( polsar ) investigates the transverse vectorial nature of plane em waves and provides the complex scattering matrix of a scatterer . scattering polarimetry is sensitive to the shape , orientation , and dielectric properties of scatters 极化合成孔径雷达( polsar )研究电磁波的矢量特征,通过测量和分析目标的极化散射特性,获取目标的介电常数、物理特性、几何形状和取向等方面的大量信息。
The precise measurement data can be useful for antenna design and slot coupling studding . this paper gives it ’ s deduction through reciprocity principle and the structure of the optically modulated scatterer system . an applied optically modulated scatterer system is designed and photodiodes are used as modulation module 本文给出以互易原理为基础的光调制散射器测量法的理论推导,并用光电二极管光导开关作为散射器中间部分的光调制单元,设计出了实用的光调制散射器微波测量硬软件系统。
