Description

technical field

[0001] The invention belongs to the technical field of antennas, in particular to a very low frequency nuclear electromagnetic pulse receiving antenna in the field. Background technique

[0002] The nuclear electromagnetic pulse is a secondary effect that must accompany the nuclear explosion, mainly due to the excitation of the gamma rays released during the nuclear explosion. The very low frequency component of the electromagnetic pulse generated by the nuclear explosion can propagate far away through the earth wave guide formed between the earth and the ionosphere, with small propagation attenuation and stable phase, and the propagation distance can reach more than thousands of kilometers. By receiving and analyzing very low frequency nuclear electromagnetic pulse waveforms, nuclear explosion events can be monitored, parameters such as nuclear explosion equivalent can be analyzed, and nuclear explosion sites can also be located through multi-station joint r...
