城市地形对电波传播的影响研究

Study on the influence of urban topography on radio wave propagation

随着科技的日新月异,我国通信技术得到飞速的发展,无线电波在人们的工作和生活中发挥越来越重要的作用。怎样提升无线电波的应用质量,是相关部门一直探索的课题。为了掌握无线电波在移动通信中的传播规律以及无线信道的特征,文章进行了城市地形对电波传播影响的试验,测量的对象是距离基站2.5 km处8个不同的测量点,测量目的是研究接收的信号电平状态和规律,并对城市地形对电波传播的影响进行研究。

With the rapid development of science and technology, China’s communications technology has been rapid development, radio waves in our work and life play an increasingly important role. How to improve the application quality of radio wave is a topic that relevant departments have been exploring. In order to master the law of radio wave propagation in mobile communication and the characteristics of the radio channel, the experiment of the influence of urban topography on radio wave propagation is carried out in this paper, the target of the measurement is 8 different measuring points at 2.5 km from the base station. The purpose of the measurement is to study the state and law of the received signal level. At the same time, the influence of multi-row buildings on the propagation of radio wave visual range is calculated, and the effect of urban topography on radio wave propagation is studied.
