摘要
从地面波传播理论出发,提出利用中频广播信号反演山体视电导率的三种方法:电场倾角反演法、地表面波阻抗反演法、透射衰减反演法,通过FEKO电磁仿真软件,建立地面波传播及透射模型,验证了三种反演方法的有效性,并结合仿真结果进一步说明实际工程测量中应注意的事项。误差对比结果表明,实际地面波传播及透射情况中,透射衰减反演法的效果优于其它两种方法。
According to the theory of ground-wave propagation,three methods are given to recover the mountain apparent conductivity by medium-wave broadcast signal:inversion of Electric field tilt angle,inversion of ground-wave impedance,inversion of transmission attenuation.The ground-wave propagation and transmission modeling is put forward,and through FEKO electromagnetic simulation the three above-mentioned methods are proved to be well consistent with the theoretical analysis.On the basis of the analysis result,some considerations for engineering measuring are illustrated.Through the error comparison between three methods,the method of inversion of ground-wave impedance is better than the others in the real ground-wave propagation and transmission situation.
