Solid State Array Studies Relevant to OTP Regulations. Part 2. Random Effects in Planar Arrays of Dipoles.

Abstract

A computer program for the analysis of random effects in planar arrays is described. The method of moments is applied iteratively in conjunction with a random sampling process, to obtain mean far field beam patterns and their expected variation. Block-Toeplitz impedance redundancies and the zeros of the excitation matrix are utilized in a special efficient solution routine. Separate array analysis at fundamental and harmonic frequencies yields the expected ratio of harmonic to fundamental levels. The theory of the computer program is outlined and typical results are presented. Significant gain degradation is predicted at harmonic frequencies. The results are applied to the OTP regulations and it is concluded that certain types of microwave solid state devices tested are viable candidates for array elements in view of these regulations.
