| Zusammenfassung |
| In November 1995 a campaign of satellite
radiotomography supported by the EISCAT incoherent scatter radar and several
other instruments was arranged in Scandinavia. A chain of four satellite
receivers extending from the north of Norway to the south of Finland was
installed approximately along a geomagnetic meridian. The receivers carried out
difference Doppler measurements using signals from satellites flying along the
chain. The EISCAT UHF radar was simultaneously operational with its beam
swinging either in geomagnetic or in geographic meridional plane. With this
experimental set-up latitudinal scans of F-region electron density are obtained
both from the radar observations and by tomographic inversion of the phase
observations given by the difference Doppler experiment. This paper shows the
first results of the campaign and compares the electron densities given by the
two methods. |
