摘　　要：随着我国信息化建设的完善,无线电业务不断增多,广播电视业务受干扰越发频繁。如何快速分析干扰台站的影响范围并制定相关解决方案,已成为无线电干扰监测的严峻考验。对此,针对监测干扰数据建立专题地理空间数据库,利用电波场强计算模型和地理信息系统(Geographic Information System,GIS)空间分析技术的组合实现广播电视监测干扰模型设计,应用GIS相关技术对干扰场强进行空间分级、动态渲染、干扰区叠置分析等操作,实现对干扰区影响范围的可视化分析,并建立GIS监测干扰服务平台,进行广播电视信号监测干扰压制覆盖分析,为广播电视信号监测提供新的解决方案。With the improvement of information construction in our country, the radio service is increasing, and the radio and television service is disturbed more and more frequently. How to quickly analyze the influence range of interference stations and formulate relevant solutions has become a serious test of radio interference monitoring. In this paper, a special geo-spatial database is established for monitoring interference data, and the radio and television monitoring interference model is designed by combining the radio field intensity calculation model and Geographic Information System(GIS) spatial analysis technology. GIS related technologies are applied to carry out spatial classification, dynamic rendering and overlay analysis of interference field intensity, and realize visual analysis of the influence range of interference area. GIS monitoring interference service platform is established to analyze interference suppression coverage of radio and television signal monitoring, providing a new solution for radio and television signal monitoring.
