PALSAR_L2.2
- SAR
Data observed by PALSAR, an L-band Synthetic Aperture Radar (SAR) on board “Daichi (ALOS)” developed by JAXA.
SAR can capture images under the same conditions as it observes the reflections of the radio waves emitted by itself. It actively emits radio waves, allowing it to observe the Earth’s surface without being limited by day or night conditions. Furthermore, since radio waves can penetrate clouds, surface observations are possible even in areas with cloud cover.
