Directive optimization of coherent sidelobe canceller systems

A method for improving interference suppression comprising:

• positioning a primary receiving sensor in a multiple signal source environment;
• placing a plurality of auxiliary receiving sensors about said primary sensor;
• receiving signals from desired and interference sources at said primary sensor to form a main channel output;
• receiving signals primarily from interference sources at said auxiliary sensors;
• supplying said primary and auxiliary sensor interference signals to a canceller system and cancelling interference in said main channel output;
• establishing a dominant azimuthal direction of interference source position along a horizontal line of sight through said primary sensor;
• arranging said auxiliary sensors in a configuration about said primary sensor such that a horizontal line of sight through any two auxiliary sensors is not parallel to a horizontal line of sight between any other two auxiliary sensors when viewed in the same horizontal plane;
• and
• moving said configuration relative to said primary sensor such that a horizontal line of sight through any two auxiliary sensors is not substantially parallel to the horizontal line indicating said azimuthal direction when viewed in the same horizontal plane.
