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 ...

High frequency surface wave radar (HFSWR) simulator [PDF]
, 2019 110 p. High Frequency (HF) - Radar ,also known as Over-The-Horizon (OTH) Radar is able to detect targets that are over the horizon up to a few hundreds kilometers, beyond the range of a conventional radar. The intrinsic properties of a HF signal enable the radio frequency (RF) signal to propagate along the earth surface. MASTER OF ENGINEERING (EEE)
