Description

technical field [0001] The invention belongs to the technical field of electromagnetic compatibility testing, and more specifically relates to a multi-dimensional remote online monitoring system for vehicle electromagnetic pulse effects. Background technique [0002] In recent years, electromagnetic pulse weapons such as high-altitude nuclear electromagnetic pulse and high-power microwave have developed rapidly, posing a serious threat to radar, communication, vehicles and other equipment. Electromagnetic pulse has the characteristics of high power, fast rise time, and wide frequency band. It can be coupled into the electronic information system through antennas, apertures, and cables, causing interference, disturbance, or even damage to sensitive circuits or devices inside the equipment. In order to evaluate the anti-electromagnetic damage capability of the vehicle, the electromagnetic pulse irradiation test of the whole vehicle is usually given priority in accordance with ...
