Abstract

In this paper, a new frequency focussing transform (FRFT) based on pseudo-inverse matrix technique is proposed for array processing of coherent wideband signals. The proposed FRFT is a non-unitary transform, but has straight-forward geometric interpretation. The computation burden is compared with those of SVD (singular value decomposition)-based frequency focussing transforms and the numerical examples are illustrated
