A new technique of analysis of unequally spaced planar arrays

The analysis of unequally spaced (thinned) arrays originated with the work of Unz (1960), and developed later, by Miller and Goodman (1983), with the application of Prony´s method to linear array synthesis. A method described earlier by the authors is extended to the analysis of planar arrays. The specific advantage of this algorithm is that the arrays currents are reconstructed in closed form, from a knowledge of limited far-zone electric field data, without the need of general matrix inversion techniques to obtain the array currents.
