SAR IMAGING USING MULTIDIMENSIONAL CONTINUOUS WAVELET TRANSFORM

Usually, in radar imaging, we suppose that the reectors re-spond the same way regardless of the angle from which they are viewed and have the same properties within the emitted frequency bandwidth. Nevertheless, new capacities in SAR imaging (large bandwidth, large angular excursions of anal-ysis) makes this assumption obsolete. The original applica-tion of the multidimensional continuous wavelet transform method in SAR imaging allows to highlight the frequency and angular behavior of these reectors. This paper discusses the utility of the wavelet transform in SAR imaging for ex-tracting from real targets some essential features allowing to distinguish objects that belong to different classes
