Spread sea clutter suppression via prior knowledge‐based space time adaptive processing in high frequency hybrid sky‐surface wave radar

open access: yesIET Radar, Sonar & Navigation, 2023
In high frequency (HF) hybrid sky‐surface wave radar, the first‐order sea clutter broadening is severe under the action of ionospheric phase disturbance and bistatic angles.

Low Observable Radar Target Detection Method within Sea Clutter Based on Correlation Estimation

open access: yesRemote Sensing, 2022
The long-time coherent integration can effectively improve the detection ability of radar targets. However, this strategy usually shows poor effect in resisting the sea clutter, which produces difficulties for accurate estimation of sea clutter ...

Infrared Small Marine Target Detection Based on Spatiotemporal Dynamics Analysis

open access: yesRemote Sensing, 2023
It is a big challenge to detect and track small infrared marine targets in non-stationary and time-varying sea clutter because the signal is too strong to be estimated.

A Knowledge-Based Auxiliary Channel STAP for Target Detection in Shipborne HFSWR

open access: yesRemote Sensing, 2021
The broadened first-order sea clutter in shipborne high frequency surface wave radar (HFSWR), which will mask the targets with low radial velocity, is a kind of classical space–time coupled clutter.

The Application of JDL to Suppress Sea Clutter for Shipborne HFSWR [PDF]

open access: yesInternational Journal of Antennas and Propagation, 2015
This paper deals with the problem of sea clutter suppression for shipborne high frequency surface wave radar (HFSWR) based on the joint domain localized (JDL) adaptive processing algorithm. The performance of the novel method is compared with 2D FFT plus digital beamforming (FFT-DBF) and orthogonal weight in different azimuths.

Bistatic Sea Clutter Suppression Method Based on Compressed Sensing Optimization

open access: yesApplied Sciences, 2023
In order to reduce the sea clutter interference in the detection of sea surface targets, we propose a bistatic sea clutter suppression method based on compressed sensing optimization in this paper. The proposed method mitigates the interference effect by

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 ...

Multichannel Sea Clutter Measurement and Space-Time Characteristics Analysis with L-Band Shore-Based Radar

open access: yesRemote Sensing, 2022
In order to study the space-time characteristics of sea clutter, the sea clutter is always measured by the airborne multichannel radar; however, the sea clutter shows the heterogeneity between range gates, which means the space-time covariance matrix’s ...

Research on Multi-Domain Dimensionality Reduction Joint Adaptive Processing Method for Range Ambiguous Clutter of FDA-Phase-MIMO Space-Based Early Warning Radar

open access: yesRemote Sensing, 2022
The ground and sea clutter received by space-based early warning radar (SBEWR) has severely range ambiguous characteristics due to its platform location, and the non-stationary factor caused by Earth’s rotation makes the received clutter at different ...
