A Sea-Surface-Zoning Method Based on Fractal Characteristics
Sensors, 2022 In this paper, a criterion for sea surface zoning based on the fractal characteristics of disturbances is demonstrated. To improve radar detection performance in heavy-tailed sea clutter, a multitude of sea clutter models and corresponding optimum and ...

Doppler characteristics of sea clutter. [PDF]
, 2010 Doppler radars can distinguish targets from clutter if the target's velocity along the radar line of sight is beyond that of the clutter. Some targets of interest may have a Doppler shift similar to that of clutter. The nature of sea clutter is different in the clutter and exo-clutter regions.

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 ...

General space-time clutter model for multi-channel airborne radar
The Journal of Engineering, 2019 Ground clutter of looking-down airborne radar is spread in Doppler because of the platform motion, and thus the interested moving targets may be masked by the ground clutter.

Terahertz High-resolution Radar Clutter Measurement and Analysis
Leida xuebao, 2015 The clutter characteristics of terahertz high-resolution radar are essential for terahertz radar detection. This study analyzes the traditional clutter probabilistic model and the corresponding parametric estimation methods.

Clutter modelling and simulation for hypersonic vehicle-borne radar
The Journal of Engineering, 2019 Hypersonic vehicles (HSV) have attracted much attention in recent years because of its military value. The radar system will face more serious clutter problem due to the increasing altitude and velocity.

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.

The neurological underpinnings of cluttering: Some initial findings [PDF]
, 2015 Background Cluttering is a fluency disorder characterised by overly rapid or jerky speech patterns that compromise intelligibility. The neural correlates of cluttering are unknown but theoretical accounts implicate the basal ganglia and medial ...
