The model for simulating the dynamic radar echo from wind turbines plays an important role in enhancing the radar antijamming capabilities of radar. However, the extensively used scattering point spacing model can hardly simulate the influence of the wind turbine's irregular blades, which makes it insufficiently accurate to simulate the radar echo from wind turbines. Therefore, the transverse arrangement is introduced to construct the irregular structure of the wind turbine's blades. Based on the waveform matching, the parameters of the transverse offset are determined, with which the improved model of the wind turbine can be constructed. The Monte Carlo algorithm is used to accelerate the process of searching for the best parameters of the transverse offset. Finally, the scaled model experiment with a GW 77/1500 wind turbine was carried out to verify the accuracy of the improved model, and the calculation times for simulating the radar echoes from 1 to 10 wind turbines were compared, which shows that the improved model can increase the accuracy of radar echo by 40% compared to the traditional model without increasing the calculation scale.
