Phased array antenna method and system for adaptively positioning nulls

摘要

A system for adaptively positioning nulls in the pattern of an antenna utilizing an auxiliary antenna in conjunction with a correlation receiver to determine the gain in amplitude and phase of the antenna pattern at the location of the interfering source. This gain is then utilized with the known gain at the peak of the main lobe of the antenna to compute coefficients of sinusoidal perturbation functions applied to the phase function of the antenna to establish a null in the direction of the interfering source.
