    • Improving the Resolution of Bearing in Passive Sonar Arrays by Eigenvalue Analysis 

      Johnson, Don; DeGraaf, Stuart (1981-08-01)
      A method of improving the bearing-resolving capabilities of a passive array is discussed. This method is an adaptive beamforming method, having many similarities to the minimum energy approach. The evaluation of energy in each steered beam is preceded by an eigenvalue-eigenvector analysis of the emperical correlation matrix. Modification of the ...
