Intelligent Suppression Method for Ionospheric Clutter Based on Clustering and Greedy Strategy
Leida xuebao, 2020 Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff, and atmospheric turbulences, and can cause serious performance ...

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 ...

Cross Beam STAP for Nonstationary Clutter Suppression in Airborne Radar [PDF]
International Journal of Antennas and Propagation, 2013 A novel space-time adaptive processing (STAP) method for nonstationary clutter suppression is proposed. The developed method forms a multibeam along the cross line to participate in adaptive processing, which sufficiently utilizes the spatial information

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.
