Space-polarization Collaborative Suppression Method for Ionospheric Clutter in HFSWR
Leida xuebao, 2016 High Frequency Surface Wave Radar (HFSWR) is able to receive surface target and low-flying aircraft echoes at a long-distance, but it suffers severely from ionospheric clutter.

Remote SensingThe non-stationary clutter of space-based early warning radar (SBEWR) is more serious than that of airborne early warning radar. This phenomenon is primarily attributed to the Earth’s rotation and range ambiguity.

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.

Remote 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 ...

Suppression of Clutter in Multichannel SAR GMTI
IEEE Transactions on Geoscience and Remote Sensing, 2014 In this paper, the results of moving-target detection in multichannel UHF-band synthetic aperture radar (SAR) data are shown. The clutter suppression is done using finite-impulse response (FIR) filtering of multichannel SAR in combination with a two-stage fast-backprojection algorithm to focus the moving target using relative speed.
