A new joint processing method based on covariance matrix fitting is presented for the multibaseline synthetic aperture radar interferometry. This can make full use of interferometric information embedded in to estimate terrain height without eigendecomposition and eigenspace division, insensitive rank variation signal subspace. By sample tapered with coherence matrix, this work robustly a finite support, which also makes it possible recover detail profile small neighbouring support. The results numerical simulations demonstrate validation proposed method.
