摘　　要：介绍了天线近场测量的历史以及中国第1个天线时域近场测量系统的建立过程和系统组成。指出时基修正和幅度修正技术是天线近场测量由理论向工程实际转化的关键技术,介绍了修正系统的构成和基本计算方法,并给出了修正前后测量结果的对比。在频域近场技术的背景下对时域近场的技术特点进行了分析,指出了天线时域近场测量技术的独到之处和应用前景。The antenna near field t history and the building process of the first antenna time domain near field measurement system in china were introduced, It .was pointed out that time base correction and amplitude correction were the key techniques in the transformation of time domain near field measurement from theories to practice. The correction system and algorithms were introduced, and the compare between the measuring results with and without correction were also presented. Based on the analysis of time domain near field technique on the background of frequency domain near field technology, the specialties and application foreground of time domain near field technique were put forward.
