摘要：
A technique is presented for determining the insertion phase of phased array elements from time-domain spectra. It is shown that the Inverse Discrete Fourier Transform (IDFT) commonly used in obtaining a time-domain spectrum yields unreliable phase results. A phase compensation to the IDFT is proposed which allows the phase of an array element to be accurately determined without explicit time-gating and without taking a second DFT. The technique is applied to determine the element insertion phases of an L-band array.
