High frequency radar clutter power for mixed ionosphere-ocean propagation
2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2014Ionospheric clutter is one of the main sources of interference affecting the performance of high frequency surface wave radar (HFSWR). One component of this arises from a portion of the transmitted radar signal which is reflected from the ionosphere to the ocean surface, from whence it is backscattered to the receiving antennas.

Sporadic-E ionospheric clutter suppression in HF surface-wave radar
IEEE International Radar Conference, 2005., 2005The unwanted radar echoes from the ionosphere are collectively called ionospheric clutter. It has proved to be the greatest impediment to achieving consistently good performance in long-range detection of surface vessels and sea state monitoring for HF surface wave radar (HFSWR).

A Model for the Ionospheric Clutter in HFSWR Radar
2008 International Conference on Information Management, Innovation Management and Industrial Engineering, 2008In order to find an effective arithmetic which can suppress the useless ionospheric clutter in a surface wave radar system, a new model for the ionospheric clutter is proposed here. Using the multiple phase-screen method used for the investigation of the HF wave propagation, the amplitude and phase scintillation of the ionospheric clutter can be ...

Robust ionospheric clutter mitigation method for high frequency surface wave radar
Science in China Series F: Information Sciences, 2008This paper analyzes the characteristics of ionospheric clutter, which has proven to be the greatest impediment in high frequency surface wave radar (HFSWR). Ionospheric clutter influences most range bins, all Doppler bins and beams, and exhibits a high directivity.

Characteristic Investigation of Ionospheric Clutter of a Coastal High-Frequency Radar
2018 OCEANS - MTS/IEEE Kobe Techno-Oceans (OTO), 2018High frequency (HF) radar can overcome the limits caused by the curvature of the earth when its electromagnetic wave operated over high conductivity sea water. The HF radar spectrum is critical for large-area current mapping because of mechanism of Bragg resonance.

Gabor feature based ionospheric clutter region extraction in Range-Doppler map
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014This paper proposes a Gabor feature based ionospheric clutter region extraction method in RD map for its good performance of picking up the orientation information from such clutter in a Range-Doppler map. The better performance of the proposed method is shown by comparing with the statistical information based and adaptive threshold based methods ...

The correlation analysis of ionospheric clutter and noise using SeaSonde HF radar
OCEANS 2017 - Aberdeen, 2017High-frequency (HF) ground wave radar's over-the-horizon property can effectively overcome the restraints posed by the curvature of the earth. HF radar transmits low-power radar waves and its detection distance is up to several hundred kilometers. However, radar in HF bands may be easily contaminated by noise, which has temporal and spatial variability,

A vertical reflection ionospheric clutter model for high frequency surface wave radar
2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015The performance of high frequency surface wave radar (HFSWR) may be significantly impacted by ionospheric clutter. A theoretical model of the ionospheric clutter for the case of vertical reflection is presented in this paper. The equation of the received electric field after vertical reflection by the ionosphere is first derived for a pulsed dipole ...

Experimental trials on ionospheric clutter suppression for high-frequency surface wave radar
IEE Proceedings - Radar, Sonar and Navigation, 2006The unwanted radar echoes from the ionosphere are collectively called ionospheric clutter. This has proved to be the greatest impediment to achieving consistently good performance in long-range sea state monitoring for high-frequency surface wave radar (HFSWR). Ionospheric clutter can mask sea echoes having similar Doppler shifts.
