Clutter reduction technique based on clutter model for automatic target classification in forward scatter radar [PDF]
, 2022 Classification becomes one of the important elements in the forward scatter radar (FSR) micro-sensors network. This classification performance is dependent on the target’s profile behaviour and the network’s surrounding; and one of the factors that cause

Research on Strong Clutter Suppression for Gaofen-3 Dual-Channel SAR/GMTI
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 ...

Ground clutter model for airborne MPRF radars in look-down search mode [PDF]
, 1996 The performances of a medium pulse repetition frequency (MPRF) radar operating in air-to-air look-down mode are strongly influenced by the presence of ground clutter.

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 ...

Deep learning‐based unmanned aerial vehicle detection in the low altitude clutter background
IET Signal Processing, 2022 Unmanned aerial vehicles (UAVs), widely used due to their low cost and versatility, pose security and privacy threats, which calls for their reliable recognition at low altitudes.

Empirical model for SAR ground clutter data
IET Signal Processing, 2017 In this study, the authors present an effective and flexible statistical model, called Burr Type‐XII distribution (BXIID), for empirical modelling of synthetic aperture radar (SAR) clutter amplitude. Also, an estimator based on method of log‐cumulants (MoLC) is proposed for the parameters of BXIID.

On differentiating ground clutter and insect echoes from Doppler weather radars using archived data [PDF]
, 2010 Normally wind measurements from Doppler radars rely on the presence of rain. During fine weather, insects become a potential radar target for wind measurement.
