A method for planar near-field to far-field transformation based on element current reconstruction is presented and the basic principle of this method is given.The results of computer simulation show that this method does not require the sampling interval to satisfy the Nyquist sampling criteria and only needs few sampling points to attain very high testing precision
so we can improve the testing speed and effectively reduce the truncation error caused by finite scanning plane on the premise of ensuring the testing precision.Therefore
the method presented in this paper is quite suitable for the planar near-field measurements with large phased array antennas.
