The invention relates to a time domain calibration method for double-exponential wave form electromagnetic pulse measurement, and solves the problem of waveform selection of a standard pulse source for calibration. Comprising the steps of 1, obtaining a frequency response curve H (j omega) of an electromagnetic pulse measurement system, and constructing a to-be-measured waveform database; 2, calculating a peak value of an output waveform after each waveform to be measured passes through the electromagnetic pulse measurement system; 3, obtaining an optional standard pulse source waveform library; 4, calculating a theoretical value of a transmission coefficient when each optional standard pulse source waveform is used for calibration; 5, calculating an error when each waveform to be measured in the database of waveforms to be measured is measured by using the transmission coefficient, obtaining an error bound of a measurement result corresponding to each selectable standard pulse source waveform, and selecting
