Analysis of the Pattern Tolerances in Linear Arrays With Arbitrary Amplitude Errors

The analysis of the tolerances on the power pattern of an array of electromagnetic radiators having excitation amplitudes affected by random errors around the nominal values is addressed. Toward this end, an analytic strategy based on interval analysis is exploited to predict the bounds of the variations in the radiated power pattern in correspondence with difference models of the amplitude tolerances. Selected results are presented and discussed in a comparative fashion as well.
