An alternate processing scheme for bearing estimation locates the peaks of the acoustic energy distribution in k-omega space and combines the estimates obtained at each temporal frequency under a least mean-square-error criterion. This processor is shown to be optimum in the sense that the variance of the resultant bearing estimate is equal to the Cramer-Rao lower bound under the same conditions assumed by MacDonald and Schultheiss. The relevance of this processing scheme for bearing estimation of impulsive signal spectra is briefly discussed in the context of recent sonar systems. Author
