Abstract

In the practice of antenna time domain planar near field measurement, the pulse generator´s time base joggling can cause very big errors in measuring results. In this paper, a time base correction technique is developed to deal with this problem. Besides measuring channel, this technique adds a reference channel in measuring system, and uses the reference channel´s time base joggling to correct the measuring channel´s signal. The practical measuring results have proved this method´s reliability.
