Incoherent Clutter Suppression Using Lag-One Coherence. [PDF]
IEEE Trans Ultrason Ferroelectr Freq Control, 2020 The lag-one coherence (LOC), derived from the correlation between the nearest-neighbor channel signals, provides a reliable measure of clutter which, under certain assumptions, can be directly related to the signal-to-noise ratio of individual channel signals.

The Impact of Model-Based Clutter Suppression on Cluttered, Aberrated Wavefronts. [PDF]
IEEE Trans Ultrason Ferroelectr Freq Control, 2017 Recent studies reveal that both phase aberration and reverberation play a major role in degrading ultrasound image quality. We previously developed an algorithm for suppressing clutter, but we have not yet tested it in the context of aberrated wavefronts.

Research on Strong Clutter Suppression for Gaofen-3 Dual-Channel SAR/GMTI [PDF]
Sensors, 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 Single-Dataset-Based Pre-Processing Joint Domain Localized Algorithm for Clutter-Suppression in Shipborne High-Frequency Surface-Wave Radar [PDF]
Sensors, 2020 Due to the motion of the platform, the spectrum of first-order sea clutter will widen and mask low-velocity targets such as ships in shipborne high-frequency surface-wave radar (HFSWR).

Transductive Radar Clutter Segmentation Network for Ionospheric Inhomogeneity Clutter Suppression
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingThe ionosphere turbulent motions, detected by radar systems, result in a complex form of ionospheric inhomogeneity clutter. In this article, we introduce transductive radar clutter segmentation network (TRCS-Net), a deep unfolding network architecture ...

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.
