Improved Mid-field Phased Array Calibration Method Based on Complex Interpolated Signals
In this brief paper, an improved method of separate amplitude and phase interpolations is presented for the mid-field phased array calibration system. Since the amplitude is relatively continuous and the phase suffers from phase wrapping, the proposed method uses linear and phase-unwrapping natural neighbor interpolation methods to reconstruct the amplitude and phase matrices, respectively. When compared with the existing work, the proposed method is more accurate under the cost-effective over-the-air testing environment.
