| Zusammenfassung |
| We present radar backscatter power measurements using the CUTLASS HF radar at
Hankasalmi, Finland from F-region field-aligned irregularities induced by HF
radio pumping with the EISCAT Heating facility. A novel radar operating mode
is used in which the radar frequency is rapidly swept through a number of
bands, making use of the varying ionospheric refraction to probe different
heights within the heated region. We obtain height profiles of backscatter
power which correspond to e-folding scale lengths of around 20km for the
mean-square electron density perturbations for pump wave interaction heights
in the region of 240-250km in daytime conditions. The results are in
agreement with previous measurements made by other techniques. We discuss
some problems with the method and suggest improvements for future
experiments. |
