Problems solved by technology
For a strong electromagnetic pulse source, due to the poor consistency of the output pulse (transient characteristics), there are large and irregular changes in the pulse amplitude, the single-point multiple test method will inevitably introduce time-varying characteristics of the radiation signal itself. In addition, the single-point multiple test method greatly increases the test time and low test efficiency; in short, the single-point multiple test method is difficult to fully meet the test requirements for the uniformity of the transient strong electromagnetic pulse field

Description
technical field [0001] The invention relates to the technical field of electromagnetic pulse field testing, in particular to a mobile transient strong electromagnetic pulse field uniformity testing device. Background technique [0002] Nuclear electromagnetic pulse is a kind of electromagnetic environment accompanied by nuclear explosion. It can generate electromagnetic radiation with very high energy in a specific area in a very short time. The high-intensity electromagnetic pulse generated is coupled by the front door (such as: antenna) or the back door. (such as: holes, cables) enter the system in two ways, interfere, disturb or even damage the sensitive electronic equipment inside the system, making it difficult for the system to effectively exert its performance. In order to ensure that electronic equipment can adapt to the external strong electromagnetic pulse environment and perform reliably, it is necessary to carry out transient strong electromagnetic environment ef...
