The partially ionized upper atmosphere can cause a variety of well-known propagation effects on radio waves including refraction, polarization rotation, group delay, scattering, and phase and amplitude fluctuations. For radar applications utilizing trans-ionospheric ray paths, these effects may result in range and look-angle errors, multi-path, non-stationary clutter and Doppler and cross-section fluctuations. The severity of these effects and their potential impact on system performance are strongly dependent on ionospheric conditions, radar parameters and the specific application under consideration. Talks in this session will provide an overview of ionospheric effects on space-based radars over a broad frequency spectrum derived from a combination of modeling techniques and actual measurements.
The Earth's ionosphere is the primary source for errors in GPS and other navigation systems. Also, regions of turbulence in the ionosphere provide disruptions of GPS and communications signals that make the systems unusable. CITRIS will provide ionospheric data that will help the Navy locate harmful regions in the ionosphere. "In the future, we expect that the CITRIS measurements will provide a warning of impending outages for both civilian and military radio systems"
Well, I looked at the URL and saw that it was Sorcha Faal's site. Is that good enough?
