摘要：

This correspondence presents a new approach for coherently focusing wide-hand data received by a linear array of sensors. The proposed preprocessing consists of adjusting the spatial sampling rate or “spatially resampling” the array outputs as a function of temporal frequency so that broad-band sources are aligned in the spatial frequency domain. Spatial resampling has the advantage that it can reduce each wide-band source in multigroup multiple source scenarios to essentially a rank one representation without preliminary estimates or a priori knowledge of the spatial distribution of the sources. © 1990 IEEE
