Method for evaluating electric field uniformity of test area of pulse excitation reverberation chamber

The invention belongs to the technical field of electromagnetic compatibility testing. The invention discloses a method for evaluating electric field uniformity of a test area of a pulse excitation reverberation chamber. The method comprises the following steps: acquiring S21 parameters at a plurality of vertexes of a test area under the position of a single stirrer through a proper amount of network analyzers, starting from a frequency domain, performing inverse Fourier transform to a time domain, intercepting a time domain signal in a time period through a time gate technology for processing, intercepting a section of signal of a source signal in the test area of a reverberation chamber through the time gate technology, and calculating an electric field intensity standard deviation and atotal standard deviation in the time gate; and finally, comparing the obtained standard deviation in the orthogonal direction and the total standard deviation with specified values of the International Electrotechnical Commi
