某地场强覆盖仿真与实测分析

为了准确客观地反映某地的电磁环境状况,运用Detvag-90电波传播模型,通过计算机仿真,得出某地的场强覆盖情况;为了验证此模型的准确性和可靠性,使用GPS接收机和便携式场强计对所选的各个测量点进行现场实测。最后,将得到的实测值与仿真值进行对比分析,从结果可以看出,实测值和仿真值误差控制在3dB以内,这说明该模型能够较好的反映该地的的电磁辐射覆盖状况,运用此方法实现对电磁环境的仿真是可行的。

Simulation and measurement analysis on field coverage in some place

In order to reflect the electromagnetic environment in a place accurately and objectively,we obtain the field coverage in a place through computer simulation using Detvag-90 electromagnetic wave propagation model.To verify the accuracy and reliability of this model,we measure the selected points using GPS receivers and field intensity meter.comparing the measured values with the simulation values,we can see,the error of measured values and the simulation values can be controlled in less than 3 dB.It shows that the model can reflect the field coverage status of electromagnetic radiation and using this method to achieve the simulation of the electromagnetic environment is feasible.
