| Abstract(in English) | We have developed a synthetic aperture radar system with 1m ground resolution compatible with 100kg small satellite. The SAR system was demonstrated in orbit by a startup company in 2021. Now we starts a new development of a small SAR system with 0.25m ground resolution. This paper describes a parallel feed slot array antenna with 1200MHz bandwidth for wide swath, a sliding spotlight mode for azimuth sweep, and developments of SAR instruments for high RF power and large data volume. |
