球面近场扫描技术中的探针补偿 PROBE COMPENSATION IN SPHERICALSCANNING IN NEAR FIELD TECHNIQUE 陈章友 Chen Zhangyou 1 first-author 孙震宇 Sun Zhenyu 1 徐鹏根 Xu Penggen 1 武汉大学电子信息学学院 武汉大学电子信息学学院 College of Electronic information , Wuhan University College of Electronic information , Wuhan University 由球矢量波函数的坐标变换关系将天线坐标系的辐射场表达式变换至探针坐标系中，利用电磁波理论中的散射矩阵理论建立了天线辐射场、探针接收特性与探针接收信号三者间的关系。这一理论将探针接收信号与探针的接收特性联系起来，考虑了球面近远场变换中的探针补偿，导体球附近振子辐射的数值结果验证了理论及计算机软件的正确性。 ln this paper . probe compensation in spherical scanning is introduced by scat- tering matrix theory. Utiliting the transformation relations of the spherical vector wave func- tion when coordinate system rotates or translates , the expressions of antenna radiating field in probe coordinate system are gotten. thus it is simple to describe their relationships of probe receiving signal , probe receiving coefficients .and antenna radiating field. 近远场变换 球面扫描 探针补偿 O438 国家自然科学基金(61672102) 1997-03-01 2021-04-01 3
