X-band Active Microwave Backscattering And Imaging Experiments In Hungary

The paper presents the status of active microwave sensor development in the X-band at the Department of Microwave Telecommunications (Dh4T), Technical University of Budapest. It includes an X-Band Scatterorneter and a Side Looking Airborne Radar (SLAR) operating in the same frequency band. The scatterorneter applies the FM/cw principle and has a dual polarized measurement capability with computer controlled data acquisition and post processing. The SLAR is a pulse modulated system, providing an average 15mx15m resolution at vertical polarization. Its data processing unit gives an on-board quick-look image and stores the acquired radar pictures for post processing in 8 bit digital form controlled by a supervising computer.
