Maximum Entropy Spectral Analysis in the Spatial Domain.

Abstract

Desirable antenna pattern characteristics include high resolution, accurate angular prediction, peak detection at low signal-to-noise power ratio levels, and stability under noisy conditions and multiple target environments. In this necessarily encompassing and cursory investigation, antenna patterns computed using MESA have exhibited these desirable properties to a relatively high degree of measure. Resolution with MESA is exceptional even under noisy conditions and in multiple and mixed target environments. High resolution is maintained even at very large angles of incidence. Estimates of signal angle appear to be quite accurate even under difficult signal conditions, and peak detection with MESA is obviously better than that provided by the Fourier transform. However, it is perhaps most significant that MESA exhibits good stability properties with use of the optimal filter size.
