First realistic modelling of the effects of Ultra Low Frequency (ULF) wave energy in the ionosphere over the Australian region

众所周知，超低频(ULF)波的活动会产生电离层电子密度的扰动。这影响了涉及电离层高频传播的技术，如超视距雷达(OTHR)和射电天文学。澳大利亚依靠OTHR利用金达利作战雷达网在我国海岸线以外进行监视。澳大利亚也在争夺下一代射电望远镜(SKA)。该项目将开发一个世界上第一个结合超低频和高频物理的模型，以进一步了解射电天文干涉仪望远镜中雷达多普勒杂波和差分相位误差的产生过程。

Ultra Low Frequency (ULF) wave activity is known to produce perturbations of the ionosphere electron density. This affects technologies that involve High Frequency (HF) propagation in the ionosphere such as over-the-horizon radar (OTHR) and radio astronomy. Australia relies on OTHR for surveillance beyond our coastline using the Jindalee Operational Radar Network. Australia is also in competition for the next generation radio telescope (the SKA). This project will develop a world first model that combines ULF and HF physics to provide advanced understanding of the generation processes of radar Doppler clutter and differential phase errors in radio astronomy interferometer telescopes.
