A Clutter Suppression Algorithm via Enhanced Sparse Bayesian Learning for Airborne Radar

IEEE Sensors Journal, 2023
The traditional space–time adaptive processing (STAP) method based on sparse Bayesian learning (SBL) has the problems of low computational efficiency and slow convergence speed.

Clutter Suppression for OTHR Based on Joint Low Rank and Group Sparse Representation

IEEE Transactions on Aerospace and Electronic Systems
Sea or ground clutter is one of the main bottleneck factors for target detection in skywave over-the-horizon radar (OTHR). Conventional methods can partly suppress clutter, however, they typically suffer from two shortcomings.

Range-Ambiguous Clutter Suppression for Space-Based Early Warning Radar Using Vertical FDA and Horizontal EPC

IEEE Geoscience and Remote Sensing Letters, 2023
The range-ambiguous clutter in space-based early warning radar is more severe compared with that in airborne radar due to the faster movement velocity. Meanwhile, the clutter angle-Doppler characteristics vary with range owing to Earth’s rotation.

A Sea Clutter Suppression Method With Graph Neural Network for Maritime Target Detection

IEEE Sensors Journal
Radar is widely applied in maritime target detection. However, the performance of sea-surface target detection in complex ocean environments is limited because of the low signal-to-clutter ratio (SCR).

CV-SAGAN: Complex-valued Self-attention GAN on Radar Clutter Suppression and Target Detection

International Radar Conference, 2023
Traditional clutter suppression and target detection methods have limitations in that they must satisfy specific statistical models. In this paper, we propose a unified deep learning model for complex-valued self-attention generative adversarial networks

Bistatic SAR Clutter-Ridge Matched STAP Method for Nonstationary Clutter Suppression

IEEE Transactions on Geoscience and Remote Sensing, 2022
Clutter suppression is a challenging task in synthetic aperture radar-ground moving target indication (SAR-GMTI). In general, sufficient secondary samples are not easily acquired due to the nonstationary and nonhomogeneous characteristics of bistatic SAR

Channel Knowledge Map-Enhanced Clutter Suppression for Integrated Sensing and Communication

2024 IEEE/CIC International Conference on Communications in China (ICCC Workshops)
Clutter suppression has been an essential problem for radar sensing, while traditional techniques such as moving target indication (MTI) and pulse Doppler (PD) usually give poor performance for slow and small targets.
