引言作为解决天线测量中某些问题的一种可能的方法,特别是从近场测量中判断误差和评价天线结构的设计特性,提出了反射体天线微波全息照像(相位和幅度)测量技术。利用这种方法所能够测出的许多天线特性中,测量整个反射体表面与理想形状的偏差是有重要意义的
INTRODUCTION As a possible method to solve some problems in the antenna measurement, especially from the judgment of the near-field measurement error and the evaluation of the design characteristics of the antenna structure, the microwave holographic imaging (phase and amplitude) measurement technology of the reflector antenna is proposed. Of the many antenna characteristics that can be measured using this method, it is important to measure the deviation of the entire reflector surface from the desired shape
