SAR Imaging Technology Makes Major Advances in China over the Past 25 Years

On September 17, 1979, scientists from the CAS Institute ofElectronics succeeded in obtaining their first microwave re-mote sensing images from a prototype airborne synthetic ap-erture radar (SAR) system. Over the past 25 years, Chinese scientistshave won many R&D results and made remarkable progress in devel-oping SAR and its ground receiving systems.The application of SAR technology is noted for its unmatchedstrong points in all-weather and around-the-clock service when pro-viding lan…
