Surface waves magnitude estimation from ionospheric signature of Rayleigh waves measured by Doppler sounder and OTH radar. [PDF]

open access: yesSci Rep, 2018
International audienceSurface waves emitted after large earthquakes are known to induce atmospheric infrasonic waves detectable at ionospheric heights using a variety of techniques, such as high frequency (HF) Doppler, global positioning system (GPS ...

Maritime over the Horizon Sensor Integration: High Frequency Surface-Wave-Radar and Automatic Identification System Data Integration Algorithm [PDF]

open access: yesSensors, 2018
To obtain the complete operational picture of the maritime situation in the Exclusive Economic Zone (EEZ) which lies over the horizon (OTH) requires the integration of data obtained from various sensors. These sensors include: high frequency surface-wave-

FREQUENCY MANAGEMENT IN HF-OTH SKYWAVE RADAR: IONOSPHERIC PROPAGATION CHANNEL REPRESENTATION [PDF]

open access: yesProgress In Electromagnetics Research B, 2013
In High-Frequency (HF) Over The Horizon (OTH) radar, the space-time variations of the ionospheric channel, the external noise level (environment and man-made) as well as the transmission channel bandwidth limitations, are among the most critical and challenging aspects for the design and the operational management.

Adaptive Transient And Cw Rf Interference Mitigation In Hf Oth Radar: Experimental Results

open access: yes, 2008
We introduce an adaptive technique for the joint mitigation of transients and continuous-wave radio-frequency co-channel interference (CW RFI) in high-frequency (HF) over-the-horizon radars (OTHRs). The performance of this technique is illustrated using data from an operational surface-wave radar (SECAR) and from recent experimental trials with sky ...

Correction of ionosphere phase contamination of high‐frequency hybrid sky‐surface wave radar using wavelet transform

open access: yesIET Radar, Sonar & Navigation, 2023
Ionospheric phase contamination (IPC) is a major contributor to the imprecise retrieval of ocean dynamics parameters by the high‐frequency hybrid sky‐surface wave radar (HFHSSW).
