Iterative FFT algorithm for thinning planar array

摘要

A new method for the synthesis of thinned periodic planar arrays with the constraint of maximum sidelobe is described in this paper. This way mainly depends on an inverse Fourier transform relationship which exists between the array factor and element excitations. Arrays can be thinned by setting the amplitudes of the element excitations to 1 and others to 0 during every iteration cycle. This paper will give the whole process of thinning planar array and specify key parts.
