Comparison of PCA and ICA based clutter reduction in GPR systems for anti-personal landmine detection [PDF]
, 2001 This paper presents statistical signal processing approaches for clutter reduction in Stepped-Frequency Ground Penetrating Radar (SF-GPR) data. In particular, we suggest clutter/signal separation techniques based on principal and independent component ...

Surface Clutter Reduction for Ground Penetrating Radar
JMECS, 2021 Surface clutter is one of the problem in GPR survey that may caused the difficulty in detecting object. The rough of the ground surface caused the surface clutter is a method for reducing the clutter is need to improved the detection result. One of method is used to achieve that objective is averaging method.

GPR Clutter Removal Based on Weighted Nuclear Norm Minimization for Nonparallel Cases
Sensors, 2023 Ground-penetrating radar (GPR) is an effective geophysical electromagnetic method for underground target detection. However, the target response is usually overwhelmed by strong clutter, thus damaging the detection performance.

A False Alarm Elimination Algorithm of Foreign Objects Debris Detection Based on Duffing Oscillator
IEEE Access, 2022 The main challenge of foreign objects debris (FOD) monitoring based on millimeter-wave (MMW) radar is the interference of strong ground clutter. The clutter-map constant false alarm rate (CM-CFAR) method is commonly utilized for FOD monitoring, but ...
