| Abstract English | This work deals with the problem of direction of arrival estimation of interferometric synthetic aperture radar (InSAR) signals in presence of layover. The focus here is on realistic acquisition systems with a low number of phase centres and nonuniform array geometry. An interpolated array approach is proposed, in order to apply spectral estimation techniques designed for uniform linear arrays. In particular, interpolated MUSIC and weighted subspace fitting (WSF) algorithms are developed and investigated. © 2004 IEEE. |
