Synthesis of a Two-Dimensional Array Antenna with elements Arbitrarily Distributed over the Plane Radiating aperture

摘要

A synthesis method is proposed in which functions describing the patterns of the array elements and a specified pattern are transformed into even function. Then, the Fourier spectra of these functions are cal- culated using the cosine Fourier transform. The amplitude-phase distribution over the array elements is deter- mined by solving a system of linear equations. It is shown that the amount of calculations in this method can be reduced (in comparison to that required in the approximation synthesis methods without any noticeable changes in the approximation to the specified pattern. This is accomplished by restricting the number of Fourier harmonics involved in the synthesis.
