Abstract:
The maximum entropy spectral analysis MESA technique is applied to a linear spatial array of sensors to obtain wavenumber power spectra. The resultant wavenumber spectra are compared with conventional beamsteered antenna patterns using simulated signals mixed with Gaussian noise. The results indicate that the MESA technique, which is an all-pole model, may provide improved accuracy and improved spatial resolution of signals under varying signal-to-noise conditions. Some difficulties with MESA are noted, and further investigations are recommended. Author
