Ground clutter characterization and elimination in mountainous terrain
A simple and fast texture-based technique for the removal of residual ground clutter is presented. Its main advantages are that it is easy to implement (both for polar and Cartesian data) and can be applied a posteriori after any other method of clutter ...

General space-time clutter model for multi-channel airborne radar
Ground clutter of looking-down airborne radar is spread in Doppler because of the platform motion, and thus the interested moving targets may be masked by the ground clutter.

Forward-Looking Super-Resolution Imaging for Sea-Surface Target with Multi-Prior Bayesian Method
Traditional forward-looking super-resolution methods mainly concentrate on enhancing the resolution with ground clutter or no clutter scenes. However, sea clutter exists in the sea-surface target imaging, as well as ground clutter when the imaging scene ...

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

Intelligent Suppression Method for Ionospheric Clutter Based on Clustering and Greedy Strategy
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
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.

In bistatic forward-looking synthetic aperture radar (BFSAR) ground moving target detection (GMTD), the suppression of the strong and heterogeneous ground clutter is one of the most crucial and challenging issues. Due to the bistatic forward-looking mode

Empirical model for SAR ground clutter data
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.

A Novel Adaptive Ground Clutter Removal Algorithm for High Range Resolution MMW Radar
In this paper we present a novel adaptive ground clutter removal algorithm for high range resolution MMW-radar application where the dielectric contrast between the air and the ground material is close to or even higher than that between the target and ...
