Remcom Selected to Develop Wind Turbine / Radar Modeling Tool
Remcom is participating on a team led by the Raytheon Company, who has been competitively selected by the US Department of Homeland Security (DHS) to develop an advanced software tool to model and assess the effects of wind turbines on radar systems used throughout the United States. Remcom is leveraging its experience with electromagnetic simulation and software optimization to provide a solution that balances fidelity and performance.

The Effects of Wind Turbines on Radar Returns
What a radar sees: RCS & Doppler vs. Time
Remcom has investigated methods for modeling the impact that wind turbines and wind farms have on radar returns. Using our XGtd tool along with novel post-processing techniques on the results, Remcom is able to simulate the magnitude and Doppler shift that would occur from radar pulses at various angles of incidence relative to the plane of rotation of the spinning blades. The rotation of the blades results in a Doppler shift that varies sinusoidally with time, as shown in the figure to the right. A summary of some of this work was presented at Milcom 2010.

Simulating Multipath Between Wind Turbines
Using XGtd, Remcom engineers can simulate the propagation paths of fields interacting with two wind turbines in close proximity. XGtd then generates a movie that shows the directions and magnitudes of the strongest propagation paths, including multipath occurring between the turbines.
The following movie clip shows directions and magnitudes of the strongest propagation paths:
