MONOSTATIC AND BISTATIC ELECTROMAGNETIC SIGNATURE OF SEA AND GROUND CLUTTER IN HF BAND ESTIMATED BY USING SPM, TSM AND SSA MODELS [PDF]
, 2012 International audienceTo cover a large area, the use of HF radars is preferred to classical radars one because HF radars are not limited by EM horizon. On counterpart, antennas of HF radars are huge and ionospheric and surface clutters disturb the use of
