Sentinel Application Platform (SNAP)

Maritime Domain Awareness (MDA) confronts significant challenges in the maritime domain, leveraging satellite technologies that play a role in enabling extensive and consistent area mapping. In this case, Synthetic Aperture Radar (SAR) stands out for its all-weather capability, serving as a crucial tool for applications ranging from environmental monitoring to defense systems (Ulaby and Long, 2014).

海上领域意识（Maritime Domain Awareness, MDA）在海事领域面临着诸多挑战。卫星技术的应用，为大范围、持续性的海域监测提供了重要支持。在该背景下，合成孔径雷达（SAR）因其全天候的能力而脱颖而出，广泛应用于环境监测、国防系统等多个领域。此外，卫星星座（satellite constellations）具备诸多优势，如全球覆盖、定期重访、远程可达以及海量数据获取能力（Sandau et al., 2010；Graziano et al., 2012）。
