High-resolution experimental dual-wavelength remote sensing synthesized aperture radar: technical appearance and flight test results

Abstract

A model of new high-resolution two-wavelength aviation synthesized aperture radar (SAR) for remote sensing of the Earth, technical appearance of the system and indicators achieved are presented in the article. The technique and results of conducted flight tests of the SAR prototype as well as examples of obtained radar images are given in the work. The achieved new SAR performance at spatial resolution was equal 0.21 m and 0.5 m in X-and L-band respectively with a viewing bandwidth at a maximum resolution of 8.4 km. In the light of the development of the use of UAVs in Russia, it is concluded that the creation of a compact version of high-resolution SAR with a reduced flight ceiling and maximum range is relevant.
