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

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

Infrared Small Marine Target Detection Based on Spatiotemporal Dynamics Analysis
Remote 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.

Target detection in high-resolution sea clutter via block-adaptive clutter suppression
IET Radar, Sonar & Navigation, 2011 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.

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