Stable MESA Antenna Patterns.

Abstract

The maximum entropy spectral analysis (MESA) technique is examined for use in computing spatial antenna patterns. The problem of split peaks is investigated, and five possible stabilization methods are examined. MESA is applied to data simulated for an 8 element antenna linear array. Split peaks are attributed to interference of noise peaks located in the vicinity of the incident signal. The split peak problem is alleviated with use of the proposed stabilization methods. Results of the investigation indicate that two of the examined averaging techniques provide excellent stabilization for MESA. Antenna patterns, computed with MESA and either of the two averaging methods, contain nearly white noise and substantially enhanced SNR. (Author)
