Simulative Investigation of the Radar Cross Section of Wind Turbines

Applied Sciences, 2019
Wind-power generation is one of the fundamental sources of renewable energy. However, due to the increasing size of wind turbines, they cause unwanted interference with radar systems for civic protection, especially for on-shore locations.

A GTD analysis of ogive pedestal [PDF]

The metal ogive pedestal is claimed to have low radar cross section and low observability features. This study uses the Geometric Theory of Diffraction (GTD) to analyze the pedestal scattering for three cases: direct backscattered field, backscattered ...

Radar cross section (RCS) measurements [Testing ourselves]

IEEE Antennas and Propagation Magazine, 2013
The radar cross section (RCS) is a critical parameter that describes the electromagnetic wave – target interaction. Its accurate prediction has long been a hot research and engineering topic. Today, RCS prediction of real targets is achieved via either numerical simulations or measurements. Here, indoor RCS measurements are reviewed in a tutorial.

AI‐Assisted Self‐Powered Wearable Dual‐Mode Sensor With TENG and Stretchable Optical Fiber for Neurological Disorder Diagnostics

Advanced Science, EarlyView.
This manuscript presents the WDMS platform, an AI‐assisted, self‐powered wearable dual‐mode sensor for tele‐neurology. It integrates a contact–separation TENG insole with stretchable polyurethane optical‐fiber strain sensors to synchronously track plantar pressure and lower‐limb muscle deformation.

Physics‐Embedded Neural Network: A Novel Approach to Design Polymeric Materials

Advanced Science, EarlyView.
Traditional black‐box models for polymer mechanics rely solely on data and lack physical interpretability. This work presents a physics‐embedded neural network (PENN) that integrates constitutive equations into machine learning. The approach ensures reliable stress predictions, provides interpretable parameters, and enables performance‐driven, inverse ...

Design and Implementation of Radar Cross-Section Models on a Virtex-6 FPGA

Journal of Engineering, 2014
The simulation of radar cross-section (RCS) models in FPGA is illustrated. The models adopted are the Swerling ones. Radar cross-section (RCS) which is also termed as echo area gives the amount of scattered power from a target towards the radar.
