According to the latest research progress of theInstitute of electronicsChinese Academy of Sciences on the miniature full polarimetric SAR flight experiment, a brief introduction of miniature SAR load and flight platform’s system composition and technical index are provided, on the basis of this, the flight experiment of polarimetricminiature SAR route planning, data processing and imaging results are emphasedin this paper. The imaging results show that four channels of full polarization micro SAR’s target is clear, the focusing effect and imaging quality are good, and the resolution is better than 0.3 m. The experiment is verified that the small light aircraft of miniature SAR system full polarization remote sensing, data acquisition and imaging processing capacity, has achieved remarkable target. This flight experimentbased onpolarimetric mini SAR remote sensing will have laid a solid foundation in variousapplications.
