Synthesis of Notched Antenna Patterns for Wide Bandwidth Processing

Abstract

Antenna patterns can be designed to have broad notches in regions where clutter and jamming are expected to be received. A number of narrowband synthesis techniques exist to design notched antenna patterns, but they break down in the presence of wideband signals on arrays which employ a combination of phase and time steering. The authors derive definitions for wideband antenna patterns and present a new synthesis procedure which can be used to design notched patterns for signals having specified bandwidths on any type of array.
