A Sea Clutter Suppression Method Based on Machine Learning Approach for Marine Surveillance Radar
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Marine surveillance radar is widely used in marine monitoring for its ability of observing sea surface all-time and all-weather. However, the radar target detection performance is seriously affected by the existence of sea clutter.

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

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.

Research on a New Comprehensive CFAR (Comp-CFAR) Processing Method
IEEE Access, 2019 Since the clutter statistics of marine radar are non-stationary and difficult to ascertain, the constant false-alarm rate (CFAR) processor based on some clutter statistical characteristics is hard to obtain the CFAR performance.

The Japan Journal of Logopedics and Phoniatrics, 2004 日本におけるcluttering症状を呈する児童の存在を仮説的に提唱し, 彼らの発話の特徴を明らかにするために, 聴覚的な印象で「発話速度が速く聞き取りづらい」と判断された児童18名を対象とし, 発話速度と非流暢性頻度 (3項目) , MLUの測定を行った.その結果, 発話特徴の結果が類似した傾向をもつ6群が浮かび上がった.6群中, 3群は「挿入・言い直し・filler」という非流暢性タイプの頻度が高い点が, 他の3群と顕著に異なっていた.また, その3群の医療的な診断歴, 知能検査, PRS検査結果の結果から, 6名全員にLD, ADHDなどの傾向が見られた.これらの特徴は欧米で研究されているclutteringの特徴と一致した.この結果から, 本研究において, (1 ...

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 ...
