摘　　要：为了更好地开展地震电离层扰动监测和异常信息提取研究,基于空间电离层环境层析成像测量仪研制了地震电离层扰动监测系统,包括小区域监测站网和监测软件系统.该监测系统产出空间分辨率1°×1°的电离层总电子含量(TEC)、F2层最大电子密度(N_(m)F_(2))和F2层峰值电子密度对应高度(h_(m)F_(2))二维分布图,对扰动异常超过10%的事件进行报警提示.实现了空间电离层层析成像测量仪在地震电离层监测领域的示范应用,并为其进一步推广应用提供了技术基础.In order to better monitor the seismic ionospheric disturbance and extract the anomaly information,a seismic ionospheric disturbance monitoring system was developed based on the space ionospheric environment tomograph,which include a small area monitoring network and software system.It could output two-dimension total electron content(TEC),the maximum electron density(N_(m)F_(2))and the corresponding peak height of the F2 layer(h_(m)F_(2))distribution map with a spatial resolution of 1°×1°.When the ionospheric disturbance exceeds 10%,alarm will be presented.The seismic ionospheric disturbance monitoring system has realized the application demonstration of space ionospheric environment tomograph in the field of seismic ionospheric monitoring.It also provides the technical basis for its further promoted application.
