Abstract
An approach of generating synthetic time domain data from frequency domain simulations in complex environments is presented in this paper. As a result, pulse forms scattered by wind turbines can be studied and compared with measurements. For large scenarios such as electromagnetic scattering from wind farms, only highfrequency methods, e.g., ray tracing can be applied. However, these methods generally operate in frequency domain, whereas measurements show the scattered pulses in time domain. The methodology presented in this paper first transfers the time domain signal to frequency domain, so the frequencydependent scattering coefficients obtained from ray tracing can be applied. Then the data is transformed back to time domain, yielding the scattered pulse in time domain.
