The invention relates to a system response correction method of a time domain electromagnetic detection system. The method is used for correcting the influence of system response on effective signals, self-adaptive output compensation is trained through theoretical and actual response of a correction device, and the influence of inherent characteristics of a receiving sensor on the effective signals is removed; and a real emission current waveform is obtained through actually measured current waveform and self-adaptive current sensor compensation, and earth response under unit step excitation is obtained according to an inverse function of the real emission current waveform. According to the method, the influence of system response on the time domain electromagnetic detection system signal can be removed, the signal quality is improved, the blind area time of system detection is reduced, and the detection range of the system is expanded.
