Blind Sea Clutter Suppression for Spaceborne GNSS-R Target Detection [PDF]
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

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 ...

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