Abstract
An examination is made of the coherent signal-subspace method for wideband direction-finding. The preprocessor consists of a multichannel finite-impulse-response filter and is suited for real-time applications. In order to accomplish faster filter design and a simple filter structure with few interconnections, band transformations are proposed. A direct approach to filter design that does not involve explicit computation of the filter response is suggested
