Determination of the radiated power of radio station through field strength measurement along a route

摘要

The paper presents a method proposed to be used for determination of the radiated power of a radio station. The proposed method is based on the comparison of field strength values measured along a route with the calculated field strength values. This method is basically frequency-independent. For the purpose of verifying efficiency of the method, signal field strength of FM broadcast radio stations was measured along several routes. The field strength in these cases was calculated using the fully featured two-ray model. The results indicated that the proposed method worked very well. The radiated power determined according to this method in the worst case was only 2.72 dB different from the actual value of the operating radiated power.
