RCS computations of targets with plasmonic coatings

EPJ 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]

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.

Radar scene generation for tactical decision aids [PDF]

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

Wideband absorptive frequency‐selective reflector based on split‐ring resonator embedded with chip resistor

Electronics Letters
Here, a wideband absorptive frequency‐selective reflector (AFSR) based on a split‐ring resonator (SRR) embedded with chip resistors is proposed. The wide absorption band is achieved by the multimode resonances of two dipoles, and the insertion of SSRs is

Narrowband Radar Micromotion Targets Recognition Strategy Based on Graph Fusion Network Constructed by Cross-Modal Attention Mechanism

Remote Sensing
In the domain of micromotion target recognition, target characteristics can be extracted through either broadband or narrowband radar echoes. However, due to technical limitations and cost constraints in acquiring broadband radar waveform data ...

Plane wave diffraction by a semi‐infinite parallel‐plate waveguide with partial material loading: The case of H polarisation

IET Microwaves, Antennas & Propagation
The analysis of diffraction by a semi‐infinite parallel‐plate waveguide with partial material loading is rigorously carried out using the Wiener–Hopf technique for the H‐polarised plane wave incidence.

Novel Electromagnetic-Based Radar Propagation Model for Vehicular Sensing

IEEE Access
With the increased carrier frequencies envisioned for future radar and communication systems, transmissions in the near-field propagation region have raised an increased interest. In order to evaluate the performance of such systems, accurate propagation
