Simplified covariance matrix measurement in adaptive arrays
D.J. Farina, Richard P. Flam · IEEE Transactions on Aerospace and Electronic Systems · 1990
A procedure to measure the covariance matrix of an antenna array directly from the array sum port is described. The procedure involves specifically chosen sets of antenna weights that will allow the matrix components to appear at the array output. A parallel method of measuring the covariance matrix is also described. The accuracy requirements of the power measurements are examined analytically and through simulation.>
