HISEA-1, the first C-band SAR small satellite for ocean remote sensing, was launched on 22 December 2020. Despite its small size, it has high spatial resolution and a large observation width, producing diverse images with rich information such as sea ice, wind, waves, ships, and oil film, making it a reliable and powerful instrument for observing oceans and lands.
On 22 December 2020, HISEA-1, the first C-band SAR small satellite for ocean remote sensing, was launched from the coastal Wenchang launch site. Though small in weight, the images it produced have a high spatial resolution of 1 m and a large observation width of 100 km. The first batch of images obtained within the first week after the launch confirmed the rich information in the data, including sea ice, wind, wave, rip currents, vortexes, ships, and oil film on the sea, as well as landmark buildings. Furthermore, geometric characteristics of sea ice, wind vector, ocean wave parameter, 3D features of buildings, and some air-sea interface phenomena in dark spots could also be detected after relevant processing. All these indicate that HISEA-1 could be a reliable, remarkable, and powerful instrument for observing oceans and lands.
