Estimation of the covariance matrix of stationary noise
Abstract
The maximum likelihood estimation of the Toeplitz covariance matrix of noise is performed. This estimation makes it possible to augment the efficiency of MTI systems given a constant repetition frequency of the sounding signal and linear arrays with equal distances between elements. An analysis is presented of the effect of the convergence speed of the estimate on the efficiency of the adaptive rejection filter, minimizing the rms error.
