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