The Optimization of Terrain Based on Daubechies4 Wavelet Transform in Complex Electromagnetic Environment

摘要：

　　The paper proposes a methodto improve the simulation speed of complex electromagnetic environment based on Ray Tracing model.As the most critical factor in complex electromagnetic environment,terrain meshing to reduce simulation time is on of the most feasible method.Do Daubechies4 two-dimensional discrete wavelet transform on the terrain DEM data to smooth the terrain to accelerate simulation.It can be seen from a large number of simulation results that DEM filter smooth processing can be adopted to improve the calculate speed while maintaining the computation accuracy simultaneously.This method can be used in optimization of complex electromagneticenvironment simulation for the radio wave propagation prediction.
