  • Abstract
    Presents the construction of an appropriate wavelet basis based on a soliton analytical model, to detect and localize these nonlinear signatures in SAR images. A local statistics filter, to suppress the speckle noise produced in the process of forming the images, is applied so as to obtain noiseless SAR images profiles. The structure of arbitrary wavelet basis derived from the generalized B-spline wavelets is studied in order to obtain a more optimal decomposition. Comparisons are made for wavelet decompositions based on several families of compactly supported wavelets
