Maximum entropy resolution of two dimensional antenna distributions

The method of Maximum Entropy Spectral Analysis is applied to several synthetic data problems, and for each case an underdetermined ensemble of radiators is resolved in magnitude and phase at a single frequency, from noiseless far-field measurements. The MESA method furnishes an estimate of the true antenna distribution based on a most probable criterion. Results show that the MESA method is most useful when estimating the qualitative nature of a distribution of line radiators, and can furnish valuable information to complement predictions from other inversion methods. In particular, it is found that the MESA method can furnish accurate phase information about those sources whose locations are indicated by the largest maximum entropy amplitudes.
