Wideband Radar Echo Frequency-domain Simulation and Analysis for High Speed Moving Targets

Leida xuebao, 2014
A frequency-domain method is proposed for wideband radar echo simulation of high-speed moving targets. Based on the physical process of electromagnetic waves observing a moving target, a frequency-domain echo model of wideband radar is constructed, and ...

The exact theory for scattering of waves by thick holes in a slab and other objects with non-separable geometries [PDF]

, 2011
The theory for scattering of electromagnetic waves is developed for scattering objects for which the natural modes of the field inside the object do not couple one-to-one with those outside the scatterer.

Computational imaging of moving objects obscured by a random corridor via speckle correlations

Nature Communications, 2022
The authors demonstrate an approach for imaging moving objects through a tortuous corridor filled with a random media. Their reduced spatial- and ensemble-speckle intensity correlation method allows for reconstruction of centimeter-sized hidden object ...

Modern nuclear force predictions for the neutron-deuteron scattering lengths [PDF]

, 2003
The nd doublet and quartet scattering lengths have been calculated based on the modern NN and 3N interactions. We also studied the effect of the electromagnetic interactions in the form introduced in AV18. Switching them off for the various nuclear force

Infrared limit in external field scattering [PDF]

, 2012
Scattering of electrons/positrons by external classical electromagnetic wave packet is considered in infrared limit. In this limit the scattering operator exists and produces physical effects, although the scattering cross-section is trivial.Comment: 12 ...

Inherent Relations among the Three Representations of Radar Target Angular Glint (in English)

Leida xuebao, 2014
Based on ElectroMagnetic (EM) theory and the monopulse radar angle measurement principle, the formulae of angular glint for complex target are proposed and generally applied to tackling practical problems.

Sea-Crossing Bridge Detection in Polarimetric SAR Images Based on Windowed Level Set Segmentation and Polarization Parameter Discrimination

Remote Sensing, 2022
As sea-crossing bridges are important hubs connecting separated land areas, their detection in SAR images is of great significance. However, under complex scenarios, the sea surface conditions, the distribution of coastal terrain morphologies, and the ...

Compton Scattering by Nuclei [PDF]

, 1999
The concept of Compton scattering by even-even nuclei from giant-resonance to nucleon-resonance energies and the status of experimental and theoretical researches in this field are outlined. Nuclear Compton scattering in the giant-resonance energy-region

SDTGAN: Generation Adversarial Network for Spectral Domain Translation of Remote Sensing Images of the Earth Background Based on Shared Latent Domain

Remote Sensing, 2022
The synthesis of spectral remote sensing images of the Earth’s background is affected by various factors such as the atmosphere, illumination and terrain, which makes it difficult to simulate random disturbance and real textures.
