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).

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.

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

Density Based Clustering Data Association Procedure for Real–Time HFSWRs Tracking at OTH Distances

open access: yesIEEE Access, 2020
In order to efficiently cover maritime areas at over the horizon (OTH) distances and thus increase marine safety in a nation's exclusive economic zone (EEZ), a network of maritime sensors built around High Frequency Surface Wave Radars (HFSWR) can be an ...
