摘　　要：增强型罗兰信号在空间传播中,受地形起伏及地貌变化的影响,信号场强呈现局部衰落特性,通过仿真分析产生这种衰落的原因,给出我国西部地区新建三个增强型罗兰发播台的信号覆盖范围,为发播台的布局提供依据。In the space propagation of enhanced Loran signal,the signal field strength presents local fading characteristic due to the influence of topographic relief and geomorphic change,through the simulation analysis of the cause of this fading,the signal coverage range of three newly built enhanced Loran broadcasting stations in western china is given,which provides the basis for the layout of broadcasting stations.

关 键 词：增强型罗兰 信号传播 覆盖范围
