We present a new empirical C-band cross-polarization ocean backscatter model for high wind retrievals, from ENVISAT-ASAR. The model relates normalized radar cross section (NRCS) in cross-polarization (VV/VH) to the wind speed at 10-m height. This wind retrieval model has the remarkable characteristic that it is independent of SAR radar incidence angles or(More)
To make sure that unmanned flight vehicle safely landed on the ground, it is necessary to control its trajectory. By adopting proper control law and optimization, the vehicle can achieve a perfect landing, and resources can be most economically assigned. It is a multi-parameters and multi-objectives optimization (MPMO) problem. Two primary problems exist in(More)
