The invention discloses a delayed sampling electromagnetic pulse detection method, relates to the technical field of electromagnetic pulse signal detection, and aims to improve the sampling rate of equipment on the premise of not changing the circuit structure of the existing detection equipment, so that the existing multi-channel detection equipment can be conveniently upgraded to have a larger signal acquisition bandwidth. Meanwhile, the bandwidth of the signal detected by the detection equipment can be doubled, the bandwidth of the signal sampled according to the sampling theorem can also be doubled, the types and information of the detected signal are richer, and for the electromagnetic pulse signal which can be covered originally, the detection efficiency is improved. By using the method, more detailed time domain information of the signal can be obtained, subsequent processing flows such as detection and identification are facilitated, and the method is suitable for large-scale popularization ...
