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

open access: yesThe 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]

open access: yes
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

open access: yesIET 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.

VHF Boundary Layer Radar and RASS [PDF]

open access: yes, 2001
This thesis describes the refinements, modifications and additions to a prototype Very High Frequency (VHF) Boundary Layer (BL) Spaced Antenna (SA) radar initially installed at the University of Adelaide's Buckland Park field site in 1997.

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

open access: yes
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 ...

RCS computations of targets with plasmonic coatings

open access: yesEPJ Applied Metamaterials, 2015
As far as RADAR Cross Section (RCS) computations are concerned, metamaterial coating modeling issues lead to cases of millions of unknowns for targets greater than the wavelength.

Venus impact craters: Implications for atmospheric and resurfacing processes from Magellan observations [PDF]

open access: yes
Observations of impact craters on Venus by Magellan yield important insights into: (1) atmospheric effects on the formation of impact craters and their attendant ejecta deposits and (2) the resurfacing history of the planet.

Introduction to radar cross-section measurements

open access: yesProceedings of the IEEE, 1965
This paper is intended to serve both as an introduction to radar cross-section measurements and as an introduction to the several measurement papers that follow in this issue. We discuss the contribution that experimental work makes to theoretical studies. The history of cross-section measurements is reviewed.

Radar scene generation for tactical decision aids [PDF]

open access: yes
The Mueller matrix and polarization covariance matrix for polarimetric radar systems was studied. The clutter was modeled by a layer of random permittivity, described by a three-dimensional correlation function, with variance, and horizontal and vertical
