Abstract :
A new phased array calibration method based on near-field measurement system such as NSI is proposed in this paper. By measuring a single element antenna near-field and array near-field, calibration parameter is extracted from measured data with twice Fourier Transformation and once Inverse Fourier Transformation. Both amplitude and phase calibration is realized by this method in a very short time. A calibration example of a one-dimensional array is used to validate the proposed method.
