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.

已知超低频（ULF）波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（HF）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使用金达利作战雷达网对我们海岸线以外的地区进行监视。澳大利亚也在竞争下一代射电望远镜（SKA）。该项目将开发一个世界上第一个结合ULF和HF物理的模型，以提供对射电天文干涉仪望远镜中雷达多普勒杂波和微分相位误差的生成过程的深入理解。
