频谱监测系统电磁态势感知模块设计

Design of Electromagnetic Situation Awareness Module for Spectrum Monitoring System

电磁态势感知是掌握电磁环境信息的重要手段。通过感知一个时空范围内的电磁环境数据,并把数据处理分析得到电磁环境的状态,再将抽象数据转化为易于理解的图像。基于分布式的频谱监测系统,该文设计了一个电磁态势感知软件模块,提出了采用Kriging插值算法计算区域内单一频点或频段的场强分布。然后结合地理信息系统,将场强数据映射为图像,实现了场强分布态势的二维可视化。解决了由点态势融合形成面态势的这一难点。

data into an easy to understand image.Based on distributed spectrum monitoring system,the paper designs an electromagnetic situation awareness software module,the Kriging interpolation algorithm is proposed to calculate field intensity distribution of a single frequency point or frequency band in the region.Combined with geographic information system,mapping field intensity data to images,the two-dimensional visualization of field intensity distribution situation is realized.The method solves the difficulty of mixing point situation to surface situation.
