Clutter rejection for MTI radar using a single antenna and a long integration time [PDF]
, 2011 Moving Target Indicators (MTI) are airborne radar systems designed to detect and track moving vehicles or aircrafts. In this paper, we address the problem of detecting hazardous collision targets to avoid them.

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 ...

A Novel Adaptive Ground Clutter Removal Algorithm for High Range Resolution MMW Radar
, 2008 In this paper we present a novel adaptive ground clutter removal algorithm for high range resolution MMW-radar application where the dielectric contrast between the air and the ground material is close to or even higher than that between the target and ...

Empirical model for SAR ground clutter data
IET Signal Processing, 2017 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]
Procedings of the British Machine Vision Conference 2007, 2007 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.

Knowledge-aided Bayesian covariance matrix estimation in compound-Gaussian clutter [PDF]
, 2010 We address the problem of estimating a covariance matrix R using K samples zk whose covariance matrices are kR, where k are random variables. This problem naturally arises in radar applications in the case of compound-Gaussian clutter. In contrast to the

A False Alarm Elimination Algorithm of Foreign Objects Debris Detection Based on Duffing Oscillator
IEEE Access, 2022 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
Sensors, 2023 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.
