Doppler shift simulation of scattered HF signals during the Tromsø HF pumping experiment on 16 February 1996
Comparisons between bistatic scatter measurements and simulation results during the Tromsø HF pumping experiment on 16 February 1996 are made. Doppler measurements of an HF diagnostic signal scattered from the field-aligned irregularities (FAIs) in the auroral E-region were carried out on the London...
