Simultaneous Altitude and RCS Estimation with Propagation Attenuation in Bistatic HFSWR
International Journal of Antennas and Propagation, 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 ...
