天线时域平面近场测试的误差分析
Error analysis on time domain planar near-field antenna measurement
摘要
Abstract
Due to less researches on the error terms, the uncertainty analysis of the test results in time domain near-field antenna measurement remains uncompleted.To solve this problem, this paper presents four error terms which are ignored or inexistent in frequency domain near-field antenna measurement: probe modulation error, source stability error, time sampling interval error and time sampling length error, and the mechanisms of these errors are discussed.Finally, influence of the errors on the experimental results is present by simulation and test after the error terms are given.关键词
