Bistatic and Stereoscopic Configurations for HF Radar

open access: yesRemote Sensing, 2020
Most HF radars operate in a monostatic or quasi-monostatic configuration. The collocation of transmit and receive facilities simplifies testing and maintenance, reduces demands on communications networks, and enables the use of established and relatively

Radar cross-section (RCS) analysis of high frequency surface wave radar targets [PDF]

open access: yes, 2010
Realistic high frequency surface wave radar (HFSWR) targets are investigated numerically in terms of electromagnetic wave - target interactions. Radar cross sections (RCS) of these targets are simulated via both the finite-difference time-domain (FDTD ...

Modified Multi-Mode Target Tracker for High-Frequency Surface Wave Radar

open access: yesRemote Sensing, 2018
In high-frequency surface wave radar (HFSWR), part of the radiation signal inevitably propagates upward and illuminates the target through the ionosphere due to the poor controllability of the antenna’s vertical pattern.

Coast–Ship Bistatic HF Surface Wave Radar: Simulation Analysis and Experimental Verification

open access: yesRemote Sensing, 2020
The coast−ship bistatic high-frequency surface wave radar (HFSWR) not only has the anti-interference advantages of the coast-based bistatic HFSWR, but also has the advantages of maneuverability and an extended detection area of the shipborne HFSWR.
