This study will investigate radar techniques and low-latitude ionospheric instability and drift processes using the Jicamarca Radio Observatory in Peru. The studies will focus on the origins of equatorial spread-F, long and short period fluctuations in ionospheric plasma drifts and their implications on the coupling of the low-latitude ionosphere to higher latitudes, generation mechanisms of the equatorial irregularities at 150 km altitude and remote sensing of those echoes, broadband measurements of the absolute scattering cross section of equatorial electrojet and 150 km irregularities, and interferometric imaging of ionospheric plasma irregularity structures. Additional research efforts will be directed toward the analysis, modeling, and development of atmospheric/ionospheric radar remote sensing techniques. ***

这项研究将利用设在秘鲁的Jicamara射电观测站调查雷达技术和低纬电离层不稳定和漂移过程。这些研究将侧重于赤道扩展F的起源、电离层等离子体漂移的长周期和短周期波动及其对低纬电离层与高纬度耦合的影响、150公里高度赤道不规则的产生机制和这些回波的遥感、赤道电喷流和150公里不规则绝对散射截面的宽带测量以及电离层等离子体不规则结构的干涉成像。更多的研究工作将针对大气/电离层雷达遥感技术的分析、建模和开发。***
