The polarimetric information of radar targets can be exploited to improve the detection performance, especially when the spatial-Doppler processing is insufficient. In the case of inhomogeneous and/or non-stationary clutters, however, the potential of the polarimetric detector is restricted due to the limited training data size, particularly when the sample support is less than the number of array...
Reflection factors are obtained for the inhomogeneous impedance plane that re-reflects the incident plane wave in a specified direction at a required polarization with a necessary frequency shift. In the general case, planes of incidence and reflection do not coincide. Results of computation are given.
Main problem of modern climatology is to assess the present as well as future climate change. For this aim two approaches are used: physic-mathematic modeling on the basis of GCMs and palaeoclimatic analogues. The third approach is based on the empirical-statistical methodology and is developed in this paper. This approach allows to decide two main problems: to give a real assessment of climate changes...
