The Discrete Convolution Method for Solving Some Large Moment Matrix Equations.

Abstract

This report describes an iterative technique to solve the matrix equation formulated by the Method of Moments. The advantage is that the number of multiplicative operations required is of the order NlogN, instead of the order N sub 2 to N sub 3 required by other solution techniques. Sample computations are made for the thin wire scatterers, linear arrays, and planar arrays. The number of iterations required for a given type of problem is found to be almost independent of the size of the matrix. The largest example given in this report is for planar array with 1849 antennas, which required four minutes of computing time on an IBM 4341. (Author)
