ASNARO-2 X-band SAR images Urban area dataset (STRIPMAP)

  • SAR

Synthetic Aperture Radar (SAR) data observed by "ASNARO-2", developed by NEC, partly funded by the Ministry of Economy, Trade and Industry.
Since SAR does not depend on light sources such as the sun, observation is possible regardless of day or night.
