The correlation analysis of ionospheric clutter and noise using SeaSonde HF radar

OCEANS 2017 - Aberdeen, 2017
High-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,

High frequency radar clutter power for mixed ionosphere-ocean propagation

2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2014
Ionospheric 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., 2005
The 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).

Spread E, F layer ionospheric clutter identification in range-Doppler map for HFSWR

2010 IEEE International Conference on Image Processing, 2010
Wide range covering, strong intensity, time-variant, fluctuation and irregular distribution of the spread E, F layer ionospheric clutter badly affects the system performance of High Frequency Surface Wave Radar (HFSWR). A spread E, F layer ionospheric clutter identification method is proposed based on the region segmentation results and region ...
