Résumé

Usually, in radar imaging, we suppose that the reflectors respond 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 analysis) makes this assumption obsolete. The original application of the multidimensional continuous wavelet transform method in SAR imaging allows to highlight the frequency and angular behavior of these reflectors. This paper discusses the utility of the wavelet transform in SAR imaging for extracting from real targets some essential features allowing to distinguish objects that belong to different classes.
