作为ELOISE实验活动的一部分，澳大利亚斜到达角（AoA）电离层探空仪网络于2015年9月安装，旨在提高对中纬度地区电离层扰动（TIDs）时空结构的理解。本文介绍了AoA测深仪的阵列设计和信号处理，并给出了典型干扰信号的采样结果。利用电子密度扰动的实际参数化模型，以及几何射线追踪，综合了中到大尺度TIDs对测深观测的影响，并有助于对测量结果进行分类。
An Australian network of oblique angle-of-arrival (AoA) ionosondes was installed as part of the ELOISE experimental campaign in September 2015, aimed at an improved understanding of the spatial and temporal structure of traveling ionospheric disturbances (TIDs) at mid-latitudes. In this paper, the array design and signal processing for the AoA sounder is described, along with a sample of results showing typical disturbance signatures. Realistic parameterized models of electron density perturbations, along with geometric ray tracing, were used to synthesize the effects of medium to large scale TIDs on the sounder observables and aid in classifying the measurements.
