Abstract

A model is described which may be used to predict land mobile radio system performance over irregular terrain. The model uses a semi-empirical formulation to calculate propagation losses from a selected base-station location to surrounding mobile locations within a variable-size "box" not exceeding two degrees latitude by two degrees longitude. Terrain data is obtained from a computer-accessible data base. The output is a plot showing contours of constant propagation loss, power density, or available received power.
不规则地形上甚高频及更高频率的陆地移动无线电系统性能模型
提出了一种可用于预测不规则地形下陆地移动无线电系统性能的模型。该模型使用半经验公式来计算从选定的基站位置到周围移动位置的传播损失,该传播损失在一个可变大小的“盒子”内,不超过2度纬度乘2度经度。地形数据是从计算机可访问的数据库获得的。输出是显示恒定传播损耗、功率密度或可用接收功率等高线的绘图。
