Noise elimination in antenna arrays with a limited number of adaptation channels
Annotation
Performance analysis of the algorithm of adaptive noise elimination is performed in multielement digital active phased antenna arrays with a limited number of control links. Modeling of digital beam-forming system characteristics has shown that restrictions on admissible bias of the maximum of the main lobe of the direction characteristic are necessary for assessment of adaptation algorithm performance quality except the criterion of signal/noise+interfering signal relation. Possibility of combination of the adaptive noise elimination method with methods of decreased side lobe level due to use of the tapered amplitudes is considered.
