Correction to "Estimating two-dimensional frequencies by matrix enhancement and matrix pencil"

The authors describe an amendment to the paper by Hua (IEEE Trans. Signal Processing, vol.40. no.9, p.2267-80, 1992). The amendment is to the tables where a numerical error was caused by a bug in the noise generation subprogram. The error was not major enough to alter any conclusion drawn. Specifically, the patterns shown in Figs. 1-8 of the original paper are actually the same as the correct ones, but the biases and deviations shown in Tables I and II should be replaced by those given in the present correction.<
