Abstract :
The authors consider the application of eigenvector techniques to the solution of interference problems. The conventional minimum-variance signal-to-noise-ratio criteria are extended to a case in which the eigenstructure of the array correlation matrix is used to cancel directional interference sources. It is shown that while the method has good interference cancellation properties, it results in higher pattern distortion than conventional arrays.<>
