A review of RFI mitigation techniques in microwave radiometry [PDF]
, 2019 Radio frequency interference (RFI) is a well-known problem in microwave radiometry (MWR). Any undesired signal overlapping the MWR protected frequency bands introduces a bias in the measurements, which can corrupt the retrieved geophysical parameters ...

Characterizing Granular Networks Using Topological Metrics [PDF]
, 2018 We carry out a direct comparison of experimental and numerical realizations of the exact same granular system as it undergoes shear jamming. We adjust the numerical methods used to optimally represent the experimental settings and outcomes up to ...

Anti-deceptive Jamming Methods Based on Single-channel Synthetic Aperture Radar
Leida xuebao, 2019 This paper discusses anti-deceptive jamming methods based on single-channel and fixed waveform assumptions for synthetic aperture radar imaging. Using the essential defects of the deceptive-jamming theory, the information acquisition ability of the ...

Research on Jamming to RF Screening Radar Based on Signal Reconstruction
Journal of Physics: Conference Series, 2020 Abstract Aiming at the problem that the jamming effect to RF screening radar by active jammer is not satisfactory, this paper provides one jamming method based on signal reconstruction. That jamming method conducts signal reconstruction based on estimation to radar signal parameters, which can achieve effective jamming to RF screening ...

A Novel Antibarrage Jamming Method for Multichannel SAR Systems Using Correlation Filtering
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingHigh-resolution wide-swath (HRWS) imaging in azimuth multichannel synthetic aperture radar (MC-SAR) is critical for remote sensing, yet electromagnetic jamming severely degrades image quality.

Isostaticity of Constraints in Jammed Systems of Soft Frictionless Platonic Solids [PDF]
, 2011 The average number of constraints per particle $$ in mechanically stable systems of Platonic solids (except cubes) approaches the isostatic limit at the jamming point ($ \rightarrow 12$), though average number of contacts are hypostatic.
