Titel
New frontend configuration of PAMIR for GMTI and interferometric SAR purposes
Abstract
A special interferometric frontend configuration of the PAMIR SAR/GMTI imaging radar, an experi-mental active phased array system with a very high simultaneous bandwidth of 1.82 GHz in X-band is described. The broadband beamforming together with azimuth wide scan capabilities (³± 45°@1.82 GHz bandwidth) requires a switchable true time de-lay network with time increments equivalent to a fraction of a wavelength. PAMIR serves as an ideal airborne platform for future broadband SAR/GMTI research activities including interferometric image formation.
