摘    要:提出了一种基于地理信息系统(geographical information system,GIS)和场强测量的辐射源位置估算方法,讨论了影响定位结果的几种可能因素(电波传播、电波传播模型误差、功率测量误差、地球曲率和介电常数),并给出了实际操作中的具体解决方案。该方法将电波传播模型和地理信息系统结合起来,利用各观测点场强测量的相对值,能有效地降低电波的绕射和多径传播的影响,较准确地实现了辐射源的位置估计,这一方法已成功地应用于某型电磁环境检测设备中。

关 键 词:GIS  场强测量  辐射源  电波传播模型  地理信息系统  位置估算  电磁环境监测

Abstract:A novel method based on geographical information system(GIS) and signal strength measurement to estimate radiatior source's location is put forward. Several infective factors, such as signal propagation, the error of signal propagation model, the curvature of earth and dielectric constant, are discussed. The plans to solve these factors are also put forward. The method combined signal propagation and GIS, using relative signal strength value, can decrease the influence of ray's diffraction and multi path propagation and realize the estimation of radiate source's location accurately. The method has been used in a radio monitoring equipment successfully.
Keywords:signal propagation model  geographic information system  location estimating
