Comparative Study on Chaos Identification of Ionospheric Clutter From HFSWR [PDF]

open access: yesIEEE Access, 2019
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 ...

Transductive Radar Clutter Segmentation Network for Ionospheric Inhomogeneity Clutter Suppression

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
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 ...

Ionospheric Clutter Suppression with an Auxiliary Crossed-Loop Antenna in a High-Frequency Radar for Sea Surface Remote Sensing

open access: yesJournal of Marine Science and Engineering, 2021
Ionospheric clutter is one of the main problems for high-frequency surface wave radars (HFSWRs), as it severely interferes with sea surface state monitoring and target detection.

Prediction method for ionospheric clutter suppression for HFSWR

open access: yesElectronics Letters, 2019
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.

Stationary Time Statistical Property of Ionospheric Clutter in High-Frequency Surface-Wave Radar [PDF]

open access: yesJournal of Electrical and Computer Engineering, 2019
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.

Space-polarization Collaborative Suppression Method for Ionospheric Clutter in HFSWR

open access: yesLeida xuebao, 2016
High Frequency Surface Wave Radar (HFSWR) is able to receive surface target and low-flying aircraft echoes at a long-distance, but it suffers severely from ionospheric clutter.

Intelligent Suppression Method for Ionospheric Clutter Based on Clustering and Greedy Strategy

open access: yesLeida xuebao, 2020
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 ...

Knowledge-Based Generalized Side-Lobe Canceller for Ionospheric Clutter Suppression in HFSWR [PDF]

open access: yesRemote Sensing, 2018
High frequency surface wave radar (HFSWR) has been successfully developed for early warning and remote sensing. However, the ionospheric clutter is a difficult challenge that can make HFSWR system inefficient.
