The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]
, 2012 We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

Calibration and Clutter Cancellation Techniques for Accurate Wideband Radar Cross Section Measurements [PDF]
, 2021 The expected received power is a key design parameter when designing a radar system. The radar’s receiver must be sensitive enough to detect the object of interest without being saturated by the highest received power. The object of interest’s visibility

Trajectory planning for uncrewed combat aircraft penetration with dynamic radar cross section constraint [PDF]
PeerJ Computer ScienceThe survivability and mission effectiveness of uncrewed combat aircraft (UCAV) is directly dependent on the probability of detection as determined by radar cross section (RCS) characteristics.

Far-field radar cross section determination using near-field ISAR imaging techniques [PDF]
, 2022 4 S.Inverse synthetic aperture radar (ISAR) imaging is a powerful tool for the characterization of radar targets. Since the direct determination of the far-field radar cross section (RCS) typically requires expensive arrangements and equipment, short ...

Polarimetric Radar Cross-Section Imaging [PDF]
, 2017 The radar cross-section (RCS) is a fundamental quantity which determines if a radar target can be reliably detected by a radar system. This quantity can be modified by altering the shape of the target.

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.
