Measured small- and broadband scattering matrix data their modeling and processing

The signal processing part of polarimetric radars works on multivariate vector sequences or partitions of scattering matrix vectors. In the case of a smallband pulse radar, the index represents SM-measurements at different time instances. In the context of broadband polarimetric radars, however, the index represents a SM-measurement taken at different carrier frequencies. The description and modeling of both types of SM-sequences and their relations to the polarimetric signal processing are the subject of this paper. Such models are of great interest because their use gives a better understanding of the reflection mechanism and allows use of model-dependent signal processing structures
