The next generation of spaceborne radar altimeter such as AltiKa or SWOT will make use of the Ka band instead of the formerly used S, C and Ku bands in order to get a better spatial resolution. As a consequence the signal will be more significantly attenuated during its way through the troposphere particularly if it rains or if there are liquid clouds. In addition, the non uniformity of the tropospheric...
This paper addresses the problem of classifying altimetric waveforms backscattered from different kinds of surfaces including oceans, ices, deserts and forests. Appropriate features associated with altimetric radar waveforms are first introduced for this classification. These features are completed by radiometer temperatures and pre-processed using a linear discriminant analysis for dimensionality...
