 在玉树地震中,中国首套自主知识产权的机载多波段多极化干涉SAR测图系统,发挥全天时主动遥感的优势,成功服务于抗震救灾中。依据玉树地震灾情综合地理信息监测与评估工作,着重探讨SAR遥感影像用于地震灾情监测与评估中的处理方法和技术路线,研究制定了地震灾区灾情综合地理信息监测指标,通过快速几何处理、快速变化信息提取、快速目标判读和灾害空间危险性评估,实现了玉树地震震区灾情综合地理信息的解译、制图和统计评估。在此基础上,开发了玉树地震灾情综合地理信息服务系统,实现了灾情监测信息的综合管理、可视化查询和统计分析。 更多还原

【Abstract】 The SAR system with its all-weather and all-time imaging capabilities emerged as a very important remote sensing data source for earthquake monitoring and disaster relief. After the recently occurred earthquake in Yushu county, Qinghai province, an airborne SAR system equipped with X-band dual antenna interferometric sensor and P-band fully polarized sensor has been successfully used in disaster monitoring and relief actions. The system is the first airborne SAR system with full intellectual pro... 更多还原
