Concept of an X-Band Synthetic Aperture Radar for Earth-Observing Satellites

摘要: This paper presents a technical concept for an X-band phased array synthetic aperture radar mounted on polar orbiting satellite. The interdependency of various parameters, such as geometric resolution, swath width and off-nadir angle, is shown well their influence the sensitivity system. A description given layout system with new dual polarized slotted waveguide attached GaAs transmit/receive modules. antenna pattern investigated specified scanning ranges in elevation azimuth direction. Descriptions are possible high resolution mode (azimuth look steering mode) survey (scan SAR). Future SAR systems require stability parameters or, at least, possibility calibrating performance operational mode. External internal radiometric calibration procedures discussed. method which monitors 64 sub-arrays can be relatively easily implemented suggested c...
