The Study of Phase Compensation in the Pattern Measurement of Certain Phase Array Antenna in Near Field

摘要

In this paper, it is discussed that phase compensation and software scheme in pattern measurement of certain phase array antenna by focusing method in near field region. A plan is used to get the phase compensation data with optics method. The phase value of every radiation element is calculated, the phase is compensated and corrected by certain arithmetic according to beam position, antenna position and distance between source antenna and the antenna under test.
