SYSTEM AND METHOD FOR PROCESSING CORRELATED CONTACTS

摘要

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 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.
