The present study considers a combination of a virtual radar and Large-Eddy Simulations (LES) to evaluate different wind profiling radar methods of estimating wind and turbulence. Measurements from the DBS method are compared with those from the Spaced Antenna (SA) method, which is a widely used technique that incorporates only a vertical beam for transmission. The backscattered signal is then received using spatially separated antennas. As a result, the SA technique relies less heavily on spatial homogeneity when compared to DBS. For this study, the DBS method was configured for five beam directions (each with a beam width of 9 degrees) in the four cardinal directions with a zenith angle of 15.5 degrees and a vertical beam. Dwell time for each beam was set to 30 s, producing a revisit time of 2.5 min. As ground truth for this study, results from both DBS and SA were compared to the "true" fields obtained directly from the LES.
