Abstract
The conventional methods can not reflect the real influence of the short-wave antennas because a shortwave broadcast station usually has many electromagnetic sources, and the distribution of electric magnetic field(EMF) in the affected area is complicated.A method using unequal mesh-size measurement based on maximum relative error control is proposed.According to the EMF changes nearby shortwave broadcast station and the feasibility of environment, the mesh-size of measurement is determined by the magnitude of the EMF gradient, adopting a high sampling rate by using small grids and a low sampling rate by using bigger grids.This method decreases the workload and keeps the high measurement precision.Applications prove that this method can get good agreements between measurement and theoretical calculation.关键词
