Abstract

The effects of correlated interference on narrowband adaptive arrays are reviewed. The performance of the spatial smoothing technique, used in a generalized sidelobe canceler with the least mean squares algorithm, is examined in terms of weight misadjustment, mean squared error, and signal-to-noise ratio. One method of combining the algorithm with spatial smoothing is shown to obey a set of nonhomogeneous dynamical equations. A numerical example is presented to support the analysis
