20. A novel antena for airborne radar : tridimensional Yagi / Um novo tipo de antena para radar aerotransportado : Yagi tridimensional
Embedded systems using Synthetic Aperture Radar (SAR), in orbital or airborne platforms, have often been used for remote sensing. When these systems are applied to vegetal cover and biomass studies, signals with frequency above 1 GHz do not properly penetrate in the vegetation. On the other hand, the use of signals with frequencies in P band (400 MHz) allows
