功能

Function

软件能够进行天线的线极化、交叉极化和圆极化性能分析;

The software can analyze the performance of linear polarization, cross polarization and circular polarization of the antenna.

软件开放测试数据的数据结构和数据格式,允许用户对测试数据进行导入或导出,可对用户导入的近场更改后的数据进行远场性能计算分析和结果输出;

The software shares the data structure and data format of the test data, allows the user to import or export the test data, and can calculate and analyze the far-field performance and output the results of the near-field modified data imported by the user;

根据采集的近场数据,软件可以快速变换出被测天线的三维远场方向图;允许用户选择多种输出坐标系等,在给定的坐标系和计算范围内,自动找出波瓣的最大点,并按两个坐标方向切面获得二维远场方向图;

According to the collected near-field data, the software can quickly transform the 3D far-field pattern of the antenna under test; The user is allowed to select various output coordinate systems, automatically find the maximum point of the lobe within the given coordinate system and calculation range, and obtain the 2D far-field pattern according to the two coordinate direction sections;

具备VBscript二次脚本开发功能

With VBscript secondary script development function.
