Transductive Radar Clutter Segmentation Network for Ionospheric Inhomogeneity Clutter Suppression

open access: goldIEEE 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 ...

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

open access: goldIEEE 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 ...

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

open access: greenLeida 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 ...

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

open access: goldJournal 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.

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

open access: goldJournal 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.

Ionospheric effects on synthetic aperture radar (SAR) clutter statistics [PDF]

open access: hybridIET Radar, Sonar & Navigation, 2013
Low‐frequency space‐based synthetic aperture radar (SAR) is an ideal sensor for measuring forest biomass, but can suffer from ionospheric effects. The variation in total electron content (TEC), originating from ionospheric turbulence, causes the along track point spread function (PSF) to degrade in a manner which depends on ...

Space‐time adaptive processing algorithm based on hyper beamforming for ionospheric clutter suppression in small‐array high‐frequency surface wave radar

open access: goldIET Radar, Sonar & Navigation, 2023
Small‐array high‐frequency surface wave radar (HFSWR) is widely used to monitor maritime targets as it can be used to save on‐land resources. In small‐array HFSWR systems, the main lobe of the receiving angle spectrum is significantly broadened.
