ESTIMATING THE FIELD-PARALLEL SCALE LENGTH OF ARTIFICIAL F-REGION STRIATIONS BY MEANS OF HF RADAR BACKSCATTER

We used the HF coherent scatter radar at Hankasalmi, Finland to observe striations generated by the EISCAT HF facility near Tromsø, Norway. By sweeping the radar frequency we can estimate the field-parallel scale length of the irregularities, since ionospheric refraction brings rays at higher freque...
