Abstract
Phased array calibration is typically carried out in
plane-wave conditions, which requires expensive far-field setups.
This letter presents a novel phased array calibration method
based on measured complex array signal, which works in the
cost-effective compact testing setup. The basic principle is to
employ multi-probe antennas in a short measurement distance
such that we can effectively retrieve the array element patterns
in the boresight direction based on the recorded complex signals
at the multiple probes using the interpolation technique. Both
theoretical derivations and measurement validations are provided
to demonstrate the effectiveness of the proposed method.
