Analysis of Current Distributions and Radar Cross Sections of Line Source Scattering from Impedance Strip by Fractional Derivative Method

Advanced Electromagnetics, 2019
In this paper, we have studied the analysis of current distributions and radar cross sections of line source scattering from impedance strip. The problem was solved with fractional derivative method previously.

Surface processes on Venus [PDF]

Magellan synthetic aperture radar (SAR) and altimetry data were analyzed to determine the nature and extent of surface modification for venusian plains in the Sedna Planitia, Alpha Regio, and western Ovda Regio areas. Specific cross sections derived from

The composite scattering model for radar sea return [PDF]

, 1972
A composite scattering model, suitable for explaining the behavior of measured scattering cross sections of the ocean surface, is presented. Furthermore, utilizing this scattering model, the spectrums of the small gravity, gravity-capillary, waves will ...

An efficient method of moments for analysis of electromagnetic scattering from a multilayered arbitrary‐shape anisotropic dielectric object

IET Microwaves, Antennas & Propagation
This paper introduces an efficient method of moments (MoM) designed to explore electromagnetic scattering in multilayered anisotropic structures. Each layer is made up of a dielectric anisotropic material characterised by a generalised tensor for ...

Insect detection and density estimation based on a Ku-band scanning entomological radar

The Journal of Engineering, 2019
Entomological radars need to address the problem of insect density estimation. Here, a Ku-band experimental entomological radar with two-dimensional scanning mode is used to collect insect echo data.

Nonprincipal plane scattering of flat plates and pattern control of horn antennas [PDF]

Using the geometrical theory of diffraction, the traditional method of high frequency scattering analysis, the prediction of the radar cross section of a perfectly conducting, flat, rectangular plate is limited to principal planes.

Dynamic RCS Simulation Using Active Frequency Selective Surface

IET Radar, Sonar & Navigation
In the experimental test of the radar system, it is extremely important to build a realistic experimental environment for electromagnetic target testing, which is often realised by the radar target simulation technology.

Polarization properties and Earth-based radar measurements of Venus in the post-Magellan era [PDF]

Studies of the polarization properties of reflected radar signals provide information about wavelength-scale surface and subsurface irregularities and can place constraints on the scattering models used to explain anomalously high backscatter cross ...
