Development and Evaluation of Adaptive Techniques for Reducing Ionospheric-Induced Radar Tracking Errors in Real Time.
Abstract
Adaptive procedures, using real time measurements of ionospheric parameters to reduce r.m.s. errors in predictions, are analyzed, addressing both additive and multiplicative processes as contributors to ionospheric variability. A particular procedure is tested using total electron content data from four stations at solar maximum and three stations at solar minimum. Its impact on radar, navigation and communication systems is evaluated, considering diurnal, seasonal and solar cycle effects. A space-time correlation cell is defined and cell limits established on the basis of temporal and spatial growth rate of r.m.s. residual error. Results indicate that an adapted prediction can significantly improve system performance, particularly in daytime at solar maximum when ionospheric refraction effects are most severe. (Author)
