The Technique of Dually Weighted Adaptive Nulls-forming in Two-dimensional Array

摘要

By analyzing the directional function of a uniform circular array,a kind of dually-weighted signal processing method of two-dimensional null-pointing technique is presented,based on maximum signal-to-noise rule and restricted main lobe qualification.Applied to a uniform two-ring circular array,the result shows that this method is valid in adaptive null-forming in case of multi-interference,and makes the main lobe point to the direction of useful signal.
