中文说明：
天线近场到远场的变换将近场区域内采集的电磁场数据进行处理，实现了将近场采样数据转换为远场方向图数据的功能，可用于评估天线性能、优化和调整，检验天线是否符合设计要求，被广泛应用于基站、星天线、雷达等领域。
English Description：
The transformation from the near-field to the far-field of the antenna is used to process the electromagnetic field data collected in the near-field region. It achieves the function of converting near-field sampling data into far-field pattern data, which can be used to evaluate antenna performance, optimize and adjust it, and check whether the antenna meets design requirements. It is widely applied in areas such as base stations, satellite antennas, radars, and so on.
