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 ...

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.

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.

Doppler polarimetric ground clutter identification and suppression for atmospheric radars based on co-polar correlation [PDF]
Journal of Telecommunications and Information Technology, 2001 A new clutter suppression technique that uses both Doppler and polarimetric information is presented. Polarimetric properties of the target and clutter are calculated per Doppler frequency cell and based on this information clutter suppression is ...

Efficient Methods of Clutter Suppression for Coexisting Land and Weather Clutter Systems [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2009 The removal of coexisting land and weather clutter signals is a common problem in many radar applications. Although the optimal method for land-weather clutter suppression is known, it is usually not amenable to implementation due to computation and storage limitations of the processor.
