Uniform 3D scattering point model for simulating the dynamic radar echo from wind farm.

The calculation scale of simulating wind farm dynamic radar echo is gradually growing with the increasing scale of wind farms, which can hardly meet the requirements of real-time radar echo simulation. Considering that the method of surface element division can greatly influence the result of simulation, uniform surface element division is applied to accelerate the traditional simulation algorithm based on the refined 3D scattering point model and enhance the main characteristics of the radar echo. The solution time of dynamic radar echoes from 1-8 wind turbines is calculated to test the average speed that the uniform 3D scattering point model can increase. The radar echo and Doppler spectrum of 4 wind turbines are simulated and analyzed as an example to verify the accuracy of the proposed model. The proposed model is demonstrated to accelerate the traditional 3D scattering point model simulation speed by 1.4 times without reducing much accuracy. [ABSTRACT FROM AUTHOR]
