HFSWR Clutter Suppression and Target Detection Method Based on RRN and Exponential Weight Control

IEEE Geoscience and Remote Sensing Letters
This letter presents a novel method for clutter suppression and target detection on the range-Doppler (RD) spectrum of a high-frequency surface wave radar (HFSWR). The approach replaces the traditional classification layer of the residual neural network (

An Extensive Cancellation Algorithm via Overlapping Subband for Time-Varying Clutter Suppression in Passive Bistatic Radar

IEEE Transactions on Aerospace and Electronic Systems
For time-varying clutter suppression in passive bistatic radar (PBR) systems, some existing clutter suppression algorithms, belonging to the time-domain filter (TDF) or the frequency-domain filter (FDF), will suffer from performance degradation in the ...

Doppler Separation-Based Clutter Suppression Method for Passive Radar on Moving Platforms

IEEE Transactions on Geoscience and Remote Sensing
For passive radar on moving platforms, the clutter suppression performance of the space–time adaptive processing (STAP) is degraded significantly. This article reveals the underlying reason that the high sidelobes of strong clutter raise the noise ...

Two-Stage Collaborative Sea Clutter Suppression Based on Subregion Gazing and Reconstruction

IEEE Geoscience and Remote Sensing Letters
Radar target detection is an important technical means for effective monitoring of sea surface targets. Under strong sea clutter, the echo characteristics of some targets with small radar cross sections (RCSs) may be submerged, affecting the performance ...

Clutter Suppression for Radar via Deep Joint Sparse Recovery Network

IEEE Geoscience and Remote Sensing Letters
In radar detection, small and slow targets are easily overwhelmed by strong clutter. Traditional methods, such as singular value decomposition (SVD) and robust principal component analysis (RPCA), can suppress clutter and recover targets by using low ...

An Attention U-Net-Based Improved Clutter Suppression in GPR Images

IEEE Transactions on Instrumentation and Measurement
The existence of strong background clutter often masks the desired target response, and thereby significantly affects the ground-penetrating radar (GPR) target detection.
