Blind Sea Clutter Suppression for Spaceborne GNSS-R Target Detection
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019 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.

Amplitude Suppression of Nongaussian Sea Clutter in a Coherent Bandpass Path of the Receiver
Известия высших учебных заведений России: Радиоэлектроника, 2016 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 ...

Bistatic Sea Clutter Suppression Method Based on Compressed Sensing Optimization
Applied 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

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 ...

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 ...
