Spatial observations by the CUTLASS coherent scatter radar of ionospheric modification 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 artificial field aligned irregularities (FAI) generated by the EISCAT (European Incoherent SCATter) he...

description | 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
artificial field aligned irregularities (FAI) generated by the EISCAT (European
Incoherent SCATter) heating facility at Tromsø, Norway. The distribution of
backscatter intensity from within the heated region has been investigated both
in azimuth and range with the Finland component of CUTLASS, and the first
observations of artificial irregularities by the Iceland radar are also
presented. The heated region has been measured to extend over a horizontal
distance of 170±50km, which by comparison with a model of the heater beam
pattern corresponds to a threshold electric field for FAI of between 0.1 and
0.01V/m. Differences between field-aligned and vertical propagation heating are
also presented. |
