Stationary Time Statistical Property of Ionospheric Clutter in High-Frequency Surface-Wave Radar
Journal of Electrical and Computer Engineering, 2019 In HFSWR (high-frequency surface-wave radar) system, the detection performance is impacted seriously by ionospheric clutter. Frequency selection is an effective method to avoid the effect of ionospheric clutter.

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

MIMO High Frequency Surface Wave Radar Using Sparse Frequency FMCW Signals [PDF]
International Journal of Antennas and Propagation, 2017 The heavily congested radio frequency environment severely limits the signal bandwidth of the high frequency surface wave radar (HFSWR). Based on the concept of multiple-input multiple-output (MIMO) radar, we propose a MIMO sparse frequency HFSWR system ...
