摘要
我国星载合成孔径雷达(SAR)面临着卫星通用性、应用维度与深度以及广域观测效能等局限性,缺少面向全球并实现长期、稳定、高性能环境动态监测的卫星系统。随着国际环境日趋复杂,我国亟需发展面向全球动态环境监测的SAR卫星系统,实现大范围、高重访、长期、稳定、高精度的对地观测。该文提出一个高频时序多维地球环境监测SAR星座(简称See-Earth)计划,从系统构想、技术体制、性能分析、应用潜力以及新体制扩展几方面来进行探讨。
The limitations of satellite versatility, application dimensions, and wide-area observation efficiency are major issues impeding the development of Chinese spaceborne Synthetic Aperture Radar(SAR). China lacks a satellite system that can realize long-term, stable, and high-performance environmental dynamic monitoring oriented to the world. As the international environment becomes increasingly complex, China urgently needs to develop a SAR satellite system for global dynamic environmental monitoring to achieve largescale, high-revisit, long-term, stable, and high-precision observations. This paper proposes a SAR Constellation with Dense Time-SEries for MultiDimensional Environmental Monitoring of the Earth(See-Earth) plan. In addition, the system conception, technical architectures, performance analysis, application potential, and new system expansion are discussed.
