基于SAR和GIS输电线路广域监测系统设计及应用

Design and Application of Wide Area Monitoring System of Transmission Lines Based on SAR and GIS

为了能够大范围、广角度地对输电线路进行监测,基于高分辨率合成孔径雷达(SAR)和遥感与地理信息系统(GIS)设计了输电线路广域监测系统。该系统以遥感监测的输电线路铁塔、输电走廊地形、违章建筑和广域火灾等雷达影像为基础,以三维GIS为平台,实现监测信息的显示、储存、分析、预警、灾后评估和决策功能。应用结果表明,该系统虽有不足,但广域监测效果及应用前景较好。

To be able to monitor the transmission lines in large-scale and wide angle, this article designs a wide area transmission lines monitoring system that depends on high-resolution synthetic aperture radar （SAR） and geographic in- formation system （GIS）. The monitoring system is based on remote monitoring of transmission line towers, transmission corridor terrain, fires and other illegal buildings and wide area radar image. Taking three-dimensional GIS as platform, the system achieves the function of monitoring information display, storage, analysis, early warning, disaster assessment and decision-making. Application results show that although the system has shortages, the wide-area monitoring effect and application have a wide prospect.
