Large eddy simulation of wake turbulence was performed by integrating the lidar measurements. Four-dimensional variational method was applied to integrate lidar measurements with the three-dimensional large eddy simulation. In addition, a bogus vortex technique was adopted to ensure the existence of wake vortices in the flow field. The validation of the method was performed by idealized test cases using virtual lidar measurement which is produced by the reference simulation of a vortex pair. The results of the validation cases showed the convergence of vortex parameters such as a circulation to that of reference simulation case. It is also confirmed that the velocity distribution on a measurement plane agrees with reference one.
