High Speed Dim Air Target Detection Using Airborne Radar under Clutter and Jamming Effects [PDF]

open access: yes, 2015
The challenging potential problems associated with using airborne radar in detection of high Speed Maneuvering Dim Target (HSMDT) are the highly noise, jamming and clutter effects.

Clutter Suppression Algorithm with Joint Intrinsic Clutter Motion Errors Calibration and Off-Grid Effects Mitigation in Airborne Passive Radars

open access: yesApplied Sciences, 2023
In an airborne passive radar, multipath (MP) clutter, which is caused by MP signals contained in the contaminated reference signal, degrades the space-time adaptive processing (STAP) performance.

Intelligent Suppression Method for Ionospheric Clutter Based on Clustering and Greedy Strategy

open access: yesLeida 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 Knowledge-Based Auxiliary Channel STAP for Target Detection in Shipborne HFSWR

open access: yesRemote Sensing, 2021
The broadened first-order sea clutter in shipborne high frequency surface wave radar (HFSWR), which will mask the targets with low radial velocity, is a kind of classical space–time coupled clutter.

Robust Space–Time Joint Sparse Processing Method with Airborne Active Array for Severely Inhomogeneous Clutter Suppression

open access: yesRemote Sensing, 2022
Due to clutter inhomogeneity, the clutter suppression ability of space–time adaptive processing (STAP) is usually constrained by the insufficient number of independent and identically distributed (IID) clutter training samples and, as a result, is ...

Eigen-based clutter filter design for ultrasound color flow imaging: A review [PDF]

open access: yes, 2010
Proper suppression of tissue clutter is a prerequisite for visualizing flow accurately in ultrasound color flow imaging. Among various clutter suppression methods, the eigen- based filter has shown potential because it can theoretically adapt its ...

Study on Sea Clutter Suppression Methods based on a Realistic Radar Dataset

open access: yesRemote Sensing, 2019
To improve the ability of radar to detect targets such as ships with a background of strong sea clutter, different sea-clutter suppression algorithms are developed based on the realistic Intelligent PIxel processing X-band (IPIX) radar datasets, and ...

Sea Clutter Suppression Using Smoothed Pseudo-Wigner–Ville Distribution–Singular Value Decomposition during Sea Spikes

open access: yesRemote Sensing, 2023
The detection of small targets within the background of sea clutter is a significant challenge faced in radar signal processing. Small target echoes are weak in energy, and can be submerged by sea clutter and sea spikes, which are caused by overturning ...

Knowledge-Aided STAP Using Low Rank and Geometry Properties [PDF]

open access: yes, 2013
This paper presents knowledge-aided space-time adaptive processing (KA-STAP) algorithms that exploit the low-rank dominant clutter and the array geometry properties (LRGP) for airborne radar applications.

Radar clutter suppression schemes

open access: yesElectronics Letters, 1984
In the letter the spatial correlation between radar clutter returns from adjacent range rings is exploited to construct two new adaptive clutter suppression schemes. The schemes are tested by using actual radar data, including weather clutter as well as ground clutter.
