摘要

摘要: GPS层析反演和电离层斜向返回探测反演可以给出电离层大尺度2维电子浓度分布，该文基于3次电离层垂测、GPS层析探测和斜向返回探测的实验结果，比较了GPS层析反演和电离层斜向返回探测反演得到的大尺度电子密度2维分布。结果表明GPS层析和电离层斜向返回探测都能较好地重构电离层电子密度分布，反映电离层大尺度的空间结构。通过和电离层垂测结果的比较，表明GPS层析和斜向返回探测反演得到电离层F2层最大电子密度和峰高具有较好的精度。

Abstract: Both GPS Computerized Ionosphere Tomography (CIT) and BackScatter Ionosonde (BSI) can provide two-dimensional electron density profile in large scale. Based on the result of three separate vertical ionosonde, GPS computerized ionosphere tomography and backscatter ionosonde, this paper compares the two-dimensional electron density profiles of GPS computerized ionosphere tomography and backscatter ionosonde. The results show that both methods reconstruct two-dimensional electron density profiles very well and reflect spatial structure of ionosphere. These two methods show high accuracy in the biggest electron density and peak height of F2 layer in contrast with the result of Vertical Ionosonde (VI).
