Study on Clutter Suppression on Ground Penetration Radar
2018 IEEE International Workshop on Electromagnetics:Applications and Student Innovation Competition (iWEM), 2018When the antenna of the underground radar is away from the ground surface, large reflection occurs on the ground surface, and it is difficult to extract weak responses in the ground and to reconstruct an image. In this paper, clutter removal means for suppressing reflection by the ground surface was studied, assuming application in landmine exploration

Ground surface scattering and clutter suppression in ground-penetrating radar applications
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012A scattering and imaging, clutter characterization and suppression study is carried out to demonstrate the feasibility of sensing buried targets in a terrain environment with a rough ground surface. The investigation is pertinent to detection performance analysis and prediction for a vehicle-based, ultra-wideband, ground-penetrating radar system.

Ground Penetrating Radar B-Scan Data Modeling and Clutter Suppression
2015 Fifth International Conference on Instrumentation and Measurement, Computer, Communication and Control (IMCCC), 2015Clutter suppression is a vital problem for Ground Penetrating Radar (GPR) signal process. The clutter suppression algorithm of GPR based on Principal Component Analysis (PCA) is concerned with the good adaptability of the ground irregularity, but there is still a problem of selecting the main components which exist in the algorithm.

Ground clutter suppression using noise radar with dual-frequency transmitter
2012 IEEE International Conference on Information Science and Technology, 2012Due to the randomness of the transmitted waveform, the range sidelobe after pulse compression of ground clutter in noise radar covers with the whole Doppler frequency domain, which forms a “noise floor” with the weaker signals drowned. Traditional moving target indicator (MTI) only applies to the radar with periodic transmitted signal for ground ...

Study on the impact of window functions in ground clutter suppression in ST radar signal spectra
TENCON 2019 - 2019 IEEE Region 10 Conference (TENCON), 2019Various signal processing window functions are applied on the back scattered signals received from the lower atmosphere by the ST radar facility at Advanced Center for Atmospheric Radar Research, Cochin. It is observed that the ground clutter present in the Doppler spectra of a particular range bin is either enhanced or suppressed with the usage of ...

Ground clutter suppression in GPR using framing based mean removal and subspace decomposition
2017 International Symposium on Antennas and Propagation (ISAP), 2017Ground penetrating radar (GPR) is one of the effective tools for detecting subsurface objects. However, the existence of ground clutter negatively affects target signal extraction particularly for shallowly buried objects and/or weak target responses. Thus, the reliable clutter suppression method is needed for enhancing the target responses. This paper

Suppression of ground clutter using an X‐band radar
Electronics and Communications in Japan (Part I: Communications), 1987AbstractMost of the clutter received by an L‐band air route surveillance radar obeys Weibull distribution with various values of the shape parameters. The L‐band radar has a frequency of 1.3 GHz and pulsewidth of 3 μs. Hence, the spatial resolution is as large as 450 m. The X‐band radar, on the other hand, ns.

A comparative analysis of the Ground clutter suppression on Meteorological images
2019 6th International Conference on Image and Signal Processing and their Applications (ISPA), 2019Local Binary Pattern (LBP) is a gray scale-invariant local operator, it is encoded with each pixel by neighbourhood thresholding which is considered as powerful and simple in the case of real-time implementation. The latter is efficient in characterizing the texture and can be adapted to different problems.

Ocean clutter suppression for an HF ground wave radar
CCECE '97. Canadian Conference on Electrical and Computer Engineering. Engineering Innovation: Voyage of Discovery. Conference Proceedings, 2002At HF frequencies, the sea echo or clutter return is quite significant and can mask signals from targets travelling at or near the same Doppler of the resonant (Bragg) ocean waves. This paper presents a systematic method of reducing clutter signals so as to enable detection of targets travelling at speeds near the Bragg Doppler.
