The First Antenna Time Domain Near Field Measurement System in China

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.
