Abstract
The paper presents a method of antenna array pattern shaping, i.e. beamforming, for Impulse Radio Ultra-Wideband (IR-UWB) correlation beamformers. The method is based on Second Cone Programming (SOCP) and allows for several parameters of shaped pattern to be simultaneously optimized; it allows for arbitrary antenna array geometry as well as for arbitrary UWB frequency-dependent radiation pattern to be considered. Before the method is described, the paper introduces time domain model of wideband antenna array along with IR-UWB correlation beamforming structure. Numerical examples using a realistic UWB antenna as an array element are also provided.
