Robustness of a correction method applied to a vertically deformed HFSWR on buoys [PDF]
, 2009 International audienceThis paper presents two correction methods for vertical deformations of the receiving array belonging to HFSWR on buoys. The method inspired from Schelkunoff's representation is more robust to the deformation's uncertainty ...

Simultaneous Altitude and RCS Estimation with Propagation Attenuation in Bistatic HFSWR
, 2013 High frequency surface wave radar (HFSWR) is traditionally unable to detect target altitude information. To simultaneously estimate the target altitude and radar cross-sections (RCS) with bistatic HFSWR, a novel estimation model is proposed with the ...
