Stationary Time Statistical Property of Ionospheric Clutter in High-Frequency Surface-Wave Radar [PDF]
In HFSWR (high-frequency surface-wave radar) system, the detection performance is impacted seriously by ionospheric clutter. Frequency selection is an effective method to avoid the effect of ionospheric clutter.

Intelligent Suppression Method for Ionospheric Clutter Based on Clustering and Greedy Strategy
Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff, and atmospheric turbulences, and can cause serious performance ...

Transductive Radar Clutter Segmentation Network for Ionospheric Inhomogeneity Clutter Suppression
The ionosphere turbulent motions, detected by radar systems, result in a complex form of ionospheric inhomogeneity clutter. In this article, we introduce transductive radar clutter segmentation network (TRCS-Net), a deep unfolding network architecture ...

Comparative Study on Chaos Identification of Ionospheric Clutter From HFSWR [PDF]
In addition to target echoes, high frequency surface wave radar (HFSWR) receives sea and ionospheric clutter. Among these clutters, the ionospheric clutter is dominant and significantly affects the detection performance of HFSWR, particularly when the ...

Prediction method for ionospheric clutter suppression for HFSWR
The detection performance of high‐frequency surface wave radar (HFSWR) is significantly impacted by ionospheric clutter and sea clutter. In order to suppress the ionospheric clutter, a new method based on the largest Lyapunov exponent prediction algorithm is proposed in this Letter.

New BSS‐based ABF for heterogeneous ionospheric clutter mitigation in HFSWR [PDF]
Ionospheric clutter is detrimental to target detection in high‐frequency surface‐wave radar (HFSWR). Adaptive beamforming (ABF) has been adopted to suppress the ionospheric clutter in recent years. Unfortunately, the performance of ABF degrades due to the heterogeneity of the ionospheric clutter.
