Spatial observations by the CUTLASS coherent scatter radar of ionospheric modi®cation by high power radio waves
Results are presented from an experimental campaign in April 1996, in which the new CUTLASS (Co-operative UK twin-located Auroral Sounding System) coherent scatter radar was employed to observe arti®cial ®eld aligned irregularities (FAI) generated by the EISCAT (European Incoherent SCATter) heating facility at Tromsù, Norway. The distribution of backscatter intensity from within the heated regi...
متن کاملVariations of topside ionospheric scale heights over Millstone Hill during the 30-day incoherent scatter radar experiment
A 30-day incoherent scatter radar (ISR) experiment was conducted at Millstone Hill (288.5 E, 42.6 N) from 4 October to 4 November 2002. The altitude profiles of electron density Ne, ion and electron temperature (Ti and Te), and line-of-sight velocity during this experiment were processed to deduce the topside plasma scale height Hp, vertical scale height VSH, Chapman scale height Hm, ion veloci...
متن کاملPassive Coherent Scatter Radar Interferometer Implementation, Observations, and Analysis
We have recently extended the passive radar technique to permit interferometric observation of ionospheric irregularities. We discuss the implementation of a passive radar interferometer at VHF frequencies and show observations of field-aligned irregularities in the high latitude E-region ionosphere. The interferometer achieves very fine azimuthal resolution (as fine as 0.1◦, or 2 km at a range...
متن کاملIonospheric climatology and variability from long-term and multiple incoherent scatter radar observations: variability
Long-term incoherent scatter radar (ISR) observations are used to study ionospheric variability for two midlatitude sites, Millstone Hill and St. Santin. This work is based on our prior efforts which resulted in an empirical model system, ISR Ionospheric Model (ISRIM), of climatology (and now variability) of the ionosphere. We assume that the variability can be expressed in three terms, the bac...
