Problems solved by technology

At present, in the research of testing, protection technology and measures of transient high-energy electromagnetic pulses, the research and development of high-energy electromagnetic pulse field generators has made great progress; however, the testing technology of high-energy electromagnetic pulse fields is relatively lagging behind and can only test Transient strong electromagnetic pulse whose rise time is above 10ns; some transient strong electromagnetic pulse test devices must be firmly fixed on the ground, and the measurement cannot be carried out when it is off the ground. In addition, the test connection line is a cable, and the test equipment is susceptible to interference. Personnel are vulnerable to electromagnetic radiation
