Recently, H. Kimura and Y. Honoki (see ibid., vol.ASSP-35, p.1024-36, July 1987) proposed a hybrid approach to high-resolution 2-D spectral estimation. However, they did not do a performance analysis of the final spectrum estimate and only conjectured that the final estimate coincides with the true maximum entropy estimate for the case of cyclic and skew-cyclic Toeplitz
