This research develops a comprehensive model of wave induced heating of the ionosphere to investigate these processes. The investigator will develop a two-dimensional model and obtain numerical solutions for specified conditions. Studies will focus on: (1) HF heating ranging from D-region to F-region of the ionosphere; (2) self-focusing instabilities induced field-aligned irregularities; (3) extremely low frequency/very low frequency generation due to temporal modulation and spatial modulation; and (4) electron energization due to the spatially localized electric fields and the associated enhancements in the optical and infrared emissions. This research will have applications in communications, underground explorations, diagnostics of ionospheric parameters, and infrared countermeasures.

这项研究开发了一个全面的电离层波感应加热模型来研究这些过程。研究人员将开发一个二维模型，并在特定条件下获得数值解。研究将集中在：(1)从电离层D区到F区的高频加热；(2)自聚焦不稳定性导致的场向不规则；(3)由于时间调制和空间调制而产生的极低频率/极低频率；以及(4)由于空间局域电场而产生的电子能量以及相关的光学和红外发射的增强。这项研究将在通信、地下勘探、电离层参数诊断和红外对抗中得到应用。
