A joint clutter suppression method based on robust principal component analysis and total variation denoising

open access: yesElectronics Letters, 2022
In the scene of ground moving target detection, the target echo information is often corrupted by strong clutter. In this letter, a joint clutter suppression algorithm is proposed based on robust principal component analysis and total variation denoising

A Clutter Suppression Method Based on LSTM Network for Ground Penetrating Radar

open access: yesApplied Sciences, 2022
It is critical to estimate and eliminate the wavelets of ground penetrating radar (GPR), so as to optimally compensate the energy attenuation and phase distortion. This paper presents a new wavelet extraction method based on a two-layer Long Short-Term Memory (LSTM) network. It only uses several random A-scan echoes (i.e., single channel detection echo

Research on Strong Clutter Suppression for Gaofen-3 Dual-Channel SAR/GMTI

open access: yesSensors, 2018
In spaceborne synthetic aperture radar (SAR), moving targets are almost buried in ground clutter due to the wide clutter Doppler spectrum and the restricted pulse repetition frequency (PRF), which increases the difficulty of moving target detection ...

A Range-ambiguous Clutter Suppression Method for MIMO Bistatic Airborne Radar

open access: yesLeida xuebao, 2018
The ground clutter of sidelooking Multiple-Input Multiple-Output (MIMO) bistatic radar has severe problems of range-dependence and clutter spectrum spreading.

A severely range ambiguous clutter suppression method based on multi‐domain cascaded signal processing for space‐based early warning radar

open access: yesIET Radar, Sonar & Navigation, 2023
The non‐stationary clutter phenomenon and the severe range ambiguity make space‐based early warning radar as an intricate model of received ground and sea clutter.

General space-time clutter model for multi-channel airborne radar

open access: yesThe 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.

Jitter-Caused Clutter and Drift-Caused Clutter of Staring Infrared Sensor in Geostationary Orbit

open access: yesSensors, 2023
For staring infrared sensors in geostationary orbit, the clutter caused by the high-frequency jitter and low-frequency drift of the sensor line-of-sight (LOS) is the impact of background features, sensor parameters, LOS motion characteristics, and ...

A Novel Clutter Suppression Approach for the Space-borne Multiple Channel in the Azimuth High-resolution and Wide-swath SAR-GMTI System with an Ambiguous Doppler Spectrum

open access: yesLeida xuebao, 2020
A low pulse repletion frequency is required and an ambiguous Doppler spectrum should be considered to obtain a high-resolution and wide-swath Synthetic Aperture Radar-Ground Moving Target Indication (SAR-GMTI) system in the azimuth direction.

Adaptive ground clutter suppression for conformal array radar systems

open access: yesIET Radar, Sonar & Navigation, 2009
Conformal arrays (CFAs) possess certain desirable characteristics for deployment on unmanned aerial vehicles and other payload-limited platforms. However, the CFA non-planar geometry induces clutter non-stationarity, resulting in elevated signal-to-interference-plus-noise ratio (SINR) loss when applying conventional space-time adaptive processing (STAP)
