A Method of Simulation and Analysis to Electromagnetic Trend for Frequency Station Based on GIS

摘要:

针对复杂电磁环境下,对电磁场强分布进行有效定量分析这一普遍存在而又难以解决的问题,提出了一种基于地理信息系统的用频台站电磁态势仿真分析方法。从三维空间地理信息系统建模、用频设备行为级仿真、电波在三维空间传播计算以及场强影响分析等几个方面,分析并实验验证该仿真方法的有效性。采用该方法可有效分析用频台站电磁态势分布和指导用频台站科学合理选址。

Abstract:

In allusion to the universal and hard task of quantitative analysis to the field strength distribution ef. fectively under complex electromagnetic environment, the method of simulation and analysis to electromagnetic trend for frequency station based on GIS was proposed, which was analyzed and validated by experiment through three dimensional GIS modeling, behavior simulation for frequency equipment, calculation to the radio-wave three dimensional propagation and impact analysis to field strength. The method could analyze electromag. netic trend distribution effectively and guide the station position selection scientifically and reasonably.
