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.

Spread E, F layer ionospheric clutter identification in range-Doppler map for HFSWR
2010 IEEE International Conference on Image Processing, 2010Wide 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 ...

Suppression of Ionospheric Es Clutter in HFSWR
2006 CIE International Conference on Radar, 2006Ionospheric clutters from sporadic E-layer are often observed in 200 km-coverage HFSWR. One kind of the Es-layer clutters is found to have coherent time much longer than that of sea echoes. The feature is exploited in the proposal of a new algorithm to suppress this kind of clutter based on eigen value decomposition and subspace ...

An analytical model for HF radar ionospheric clutter
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013In this paper, an analytic model for the mixed path mode of ionospheric clutter associated with high frequency surface wave radars (HFSWR) operating in an ocean environment is presented. Based on earlier work, an expression for the first-order received electric field after a single scatter from each of the ionosphere and sea surface is derived and ...

Characteristic research of ionospheric clutter in over the horizon HFSWR
IET Conference Publications, 2009The presence of ionospheric clutter in high-frequency over the horizon surface wave radar may extremely affect the performance of radar system and degrade the capability of detecting target, so it should be suppressed. The characteristic analysis of ionospheric clutter is the foundation of studying method to suppress ionospheric clutter, so it is ...

Ionospheric Clutter Suppression in HF Surface Wave Radar
Journal of Electromagnetic Waves and Applications, 2009The ionospheric clutter has been proved to be one of the dominant clutters degrading the performance of the HF surface-wave radar (HFSWR) severely, so suppressing the ionospheric clutter is a vital part of radar signal processing sequence. In this paper, the spatial characteristics of the ionospheric clutter in a planar array are analyzed, then a new ...

An ionospheric clutter recognition method based on machine learning
2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017Ionospheric clutter is the primary factor that affecting High Frequency Surface Wave Radar (HFSWR) detection performance. In order to draw up an adaptive detection strategy suitable in various environment, a novel algorithm is proposed in this paper to recognize ionospheric clutter.
