基于崎岖度法的调频场强计算与测量分析

Calculation and Measurement Analysis of FM Field Strength Based on Degree of Roughness

本文基于“崎岖度法”理论,详细阐述了调频覆盖场强的计算方法,包括有效辐射功率、天馈线增益、天线有效高度、地形衰减校正系数的计算方法以及接收天线的补偿计算。通过实例计算并与测量数据进行比较,本文深入分析了接收点地形和菲涅尔区等因素对实测结果的影响。

Based on the theory of the degree of roughness,this paper elaborates on the calculation methods of the effective radiation power,antenna feeder gain,antenna effective height,terrain attenuation correction coefficient,and the compensation calculation of the receiving antenna.By contrasting and analyzing calculation results and factual measurement statistics,the paper sheds further light on the possible effect on measurement results exerted by various factors like the terrain features of the receiving point and Fresnel area.
