A comparison of satellite scintillation measurements with HF radar backscatter characteristics [PDF]
Annales Geophysicae, 2005 We examine the correspondence between high latitude ionospheric scintillation measurements made at 250MHz with the occurrence of 10MHz HF coherent radar backscatter, on 13 and 14 December 2002.

Validation of HF Radar Measurements [PDF]
Oceanography, 1997 made? H F RADARS ARE A UNIQUE and powerful tool for measuring surface currents. They provide an unpa ra l l e l ed window into the spat ial var ia t ions of near-surface currents. But oceanographers who are more accus tomed to measur ing currents with instruments that actually get wet may reasonably ask how accurate can such remote measurements be made?
