Investigation of the restrictions on the shape of the radiation pattern of an adaptive antenna array

An algorithm for adapting the radiation pattern of an antenna array to the jamming conditions is described, based on direct inversion of the covariance matrix of the input signals, with a new method of restricting the shape of the radiation pattern for this algorithm.
