Blind Sea Clutter Suppression for Spaceborne GNSS-R Target Detection
It has been demonstrated that delay-Doppler (DD) maps (DDMs) retrieved from spaceborne Global Navigation Satellite Systems Reflectometry missions contain sea clutter and also potential sea targets. Examples of sea targets include sea ice, oil rigs, and oil slicks.

Target detection in high-resolution sea clutter via block-adaptive clutter suppression
Attentions have been focused on the moving target detection in a high-resolution sea clutter. This study commences with a proposal of median-based estimator to estimate the power spectrum of high-resolution sea clutter by the time series observed in adjacent range cells and time intervals.

Amplitude Suppression of Nongaussian Sea Clutter in a Coherent Bandpass Path of the Receiver
The method of non-linear amplitude suppression of radar clutter from a sea surface in the coherent band path of the receiver is considered. The model of the most adequate nongaussian radar clutter from the rough sea surface which envelope is based on K ...

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

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

Infrared Small Marine Target Detection Based on Spatiotemporal Dynamics Analysis
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.

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