Ionospheric Polarization Techniques for Robust NVIS Remote Sensing Platforms

Every year more interest is focused on high frequencies (HF) communications for remotesensing platforms due to their capacity to establish links of more than 250 km without a line ofsight and due to them being a low-cost alternative to satellite communications. In this article, westudy the ionospher...
