Title:
Wideband Direction-of-Arrival Estimation Using Spatially Interpolated Wideband Beamformers 
Abstract:
We present a new method for wideband direction-of-arrival (DOA) estimation, based on a spatially interpolated wideband beamformer (SIWB). The SIWB is designed to have a frequency-invariant beam-response, prescribed main beamwidth and prescribed sidelobe level within a wide signal bandwidth. For wideband DOA estimation, the SIWBs can be used as spatial preprocessors transforming the wideband signals at the outputs of an antenna array (element-space) into the beam-space signals prior to applying n...    »
