Adaptive synthesis of antennas with separation of signals by direction of arrival

A model is developed of an adaptive procedure for synthesizing an antenna with signal separation by direction of arrival, which employs phase processing in the aperture of a phase array. The model makes it possible to identify the basic regularities in the relationship between the rate of convergence, and the signal division efficiency, as a function of the parameters of the algorithm and the device which implements the processing. The model is helpful during the initial stage of the synthesis, because it makes it possible to reduce the region in which the optimizing parameters are sought. The modeling of an adaptive processing of reducing the directivity pattern level in the direction of the source of an interferring signal for a 200-element flat switched phased array is presented as an example.
