Simultaneous frequency and bearing estimation using 2-D spectral analysis of the space-time data array is investigated. The spectral estimates are generated using 2-D linear prediction. It is shown that single-quadrant prediction can lead to severe asymmetry and bias in the estimated spectra; while a certain combination of the results for two adjacent quadrants yields well-behaved spectral estimates.
