2026-06-25 HS-NH-1.0 High-Resolution Marine Multi-Target Monitoring SAR Dataset doi:10.57760/sciencedb.35543 en The HS-NH-1.0 dataset is a SAR dataset designed for high-resolution ocean monitoring, supported by the Hainan Aerospace Technology Innovation Center. Hainan Province's aerospace technology innovation has jointly developed two satellites with Zhongke Satellite Technology Group, namely "Haishao-1 (HS-01)"/AIRSAT-08 satellite and "Haishao-2 (HS02)"/AIRSAT-05 satellite. All of them have successfully operated in orbit, with one optical SAR collaborative satellite and one SAR satellite, possessing the ability to acquire and service space remote sensing data 24/7, multi means, high-frequency, and low-cost. This dataset covers multi-source image data obtained by HS series satellites in different working modes and frequency bands. Typical scene samples from multiple time periods were selected, consisting of 25 sets of HS-01 and HS-02 satellite data from different regions. HS-01 satellite adopts X-band, dual polarization (HH+HV) stripe mode with a resolution of 1m and a width of 10km; HS-02 satellite adopts X-band, dual polarization (HH+HV) stripe mode with a resolution of 3m and a width of 30km. All images are L2 level system geometric correction products, which complete geometric positioning, map projection, and resampling processing based on satellite attitude and orbit data, with accurate spatial reference and geometric consistency. The data format is GeoTIFF. The data coverage is extensive, including atmospheric ducts, ocean fronts, internal waves, eddies and other ocean dynamic processes, as well as typical offshore targets such as wind farms, marine aquaculture, and ships, providing diverse sample support for monitoring ocean dynamic processes and ocean targets.  SAR; HS-NH-1.0; ocean monitoring Li Xiaoming Lu Xingqiang Li Xing PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
