SAR卫星遥感影像

自主发射38颗卫星组建女娲星座，包括28 颗雷达卫星组成的雷达遥感星座和10 颗全色0.5 米八谱段以及多光谱2米的光学卫星组成的光学遥感星座。具备高精度地形测绘、高分宽幅成像、形变检测以及三维立体成像等能力,分辨率达到0.5米-5米。可快速、高效地制作高精度数字表面模型（DSM）并完成全球非极区测绘任务，可实现同一区域1小时快速重访，15天全国覆盖，40天全球覆盖。

Thirty-eight satellites have been independently launched to establish the Nüwa Constellation, which consists of two segments: a radar remote sensing constellation with 28 radar satellites, and an optical remote sensing constellation equipped with 10 optical satellites featuring 0.5-meter panchromatic 8-band and 2-meter multispectral specifications. The constellation supports capabilities including high-precision topographic mapping, high-resolution wide-swath imaging, deformation detection, and 3D stereoscopic imaging, with a spatial resolution ranging from 0.5 meters to 5 meters. It can rapidly and efficiently generate high-precision Digital Surface Models (DSM) and complete global non-polar region mapping missions. Furthermore, it enables rapid revisit of the same target region within 1 hour, full national coverage within 15 days, and global coverage within 40 days.
