Null synthesis with phase and amplitude controls at the subarray outputs
Abstract
This report investigates the generation of nulls in an antenna pattern by controlling the phase and amplitude of the subarray output signals. Although the nulls may be formed with any number of subarrays, the subarray configuration and desired null location have a major impact on the distortion problem resulting from subarray nulling is well known, but little theoretical analysis has been done to explain the cause of the distortion. This report offers a theoretical and graphical explanation of why the distortion occurs.
