Abstract
A system and process for maintaining correlated contacts (e.g., sonar/radar contacts) utilizes diagonal averaging. A covariance matrix is formed from signals received by an array of sensors. These sensors may be acoustic and/or electromagnetic sensors. The covariance matrix is replaced with Toeplitz matrix. The Toeplitz matrix is a Toeplitz matrix that most closely matches the covariance matrix in the least squares sense. The Toeplitz matrix is used to calculate weight vectors for the adaptively formed response signals.
