The invention relates to a time-domain calibration method for an electromagnetic pulse magnetic-field probe. The method is used for calibrating an electromagnetic pulse magnetic-field probe in the time domain. The method comprises an anechoic chamber, a pulse signal source, a transmitting antenna, a standard receiving antenna, and a digital oscilloscope. According to the method, the transmitting antenna and the standard receiving antenna are placed at fixed places in the anechoic chamber, and the pulse signal source and the digital oscilloscope are placed in an anechoic chamber control room. A pulse voltage signal is fed into the transmitting antenna via a through-wall cable by the pulse signal source, and the transmitting antenna radiates an electromagnetic pulse to the outside. The standard receiving antenna receives the pulse electric field radiated from the transmitting antenna. The digital oscilloscope is connected with the receiving antenna and a to-be-calibrated magnetic-field probe via another through-wall cable so as to record a voltage signal waveform measured by the receiving antenna and the to-be-calibrated magnetic-field probe. Measured voltage signals are processed based on a certain algorithm, so that the time-domain transfer function of the to-be-calibrated magnetic-field probe is obtained. In this way, the time-domain calibration on the electromagnetic pulse magnetic-field probe can be realized.
