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 ...

Empirical model for SAR ground clutter data
In this study, the authors present an effective and flexible statistical model, called Burr Type‐XII distribution (BXIID), for empirical modelling of synthetic aperture radar (SAR) clutter amplitude. Also, an estimator based on method of log‐cumulants (MoLC) is proposed for the parameters of BXIID.

An Automatic Framework for Figure-Ground Segmentation in Cluttered Backgrounds [PDF]
This paper proposes an automatic framework for figure-ground segmentation of edged images in the presence of cluttered background. Our work employs perceptual grouping concepts to characterize image segments by means of their saliency, which is computed via tensor voting.

A False Alarm Elimination Algorithm of Foreign Objects Debris Detection Based on Duffing Oscillator
The main challenge of foreign objects debris (FOD) monitoring based on millimeter-wave (MMW) radar is the interference of strong ground clutter. The clutter-map constant false alarm rate (CM-CFAR) method is commonly utilized for FOD monitoring, but ...

GPR Clutter Removal Based on Weighted Nuclear Norm Minimization for Nonparallel Cases
Ground-penetrating radar (GPR) is an effective geophysical electromagnetic method for underground target detection. However, the target response is usually overwhelmed by strong clutter, thus damaging the detection performance.
