A Method For Beat-Wave Measurement And Uncertainty Analysis

Beat-wave is an important technique to improve the microwave radiation power. It is a new method to measure beat-wave radiation field by combining and calculating the space electric field separated from the beat-wave signal. This method solved the problem that it was difficult to determine the working frequency of the detector and the corresponding technical index because of the non-linear characteristics of the geophone in the traditional measurement method. According to the measuring principle of this method, the evaluation method and results of uncertainty were given on X-band in the paper.
