Research on the Ground Penetrating Radar Clutter Suppression Technology Based on PCA Method [PDF]

Advances in Computer Science Research, 2015
The reduction of background clutter signal from Ground Penetrating Radar (GPR) experiments is an area of active research. The weak reflection signal obtained from subsurface targets is usually blurred by such strong clutter. Therefore, clutter suppression is the key step in ground penetrating radar signal processing.

Experimental Analysis of a Clutter Suppression Algorithm for High Time-Bandwidth Noise Radar

, 2023
Noise-like, continuous waveforms have several benefits for radar operation, such as low probability of interception/identification. However, the same types of waveforms come with a significant drawback because strong signals, e.g., ground clutter ...

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

Advanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).
