Strong electromagnetic pulse test verification ability Get!

In recent years, the military reform with information technology as the core is competing among countries in the world.It has become a new stage for the military wrestling of various countries to pay attention to the invisible electromagnetic space and advance the research of training and operation under the complex electromagnetic environment.

As a transient electromagnetic phenomenon, strong electromagnetic pulse, in the form of space radiation transmission, can cause damage to electronic, information, electricity, photoelectricity, microwave and other facilities, which can seriously interfere the electronic equipment and ground control system on the unguarded missile or satellite and even lose normal working capacity. From the last centuryIn the 1970s, foreign military attaches great importance to the basic research of electromagnetic environment effect and protection and reinforcement of weapon equipment, as well as the simulation and experimental research. In the past two years, western countries, led by the United States, have repeatedly emphasized the threat of electromagnetic pulse from high-altitude nuclear explosion to weapon systems. China also attaches great importance to the threat of strong electromagnetic pulse to military, power and other fields, and accelerates the construction of protective capacity from a strategic height.

As a military computer research institute, from the tenth five-year plan to the thirteenth five-year plan, our institute has been carrying out basic research on anti-strong electromagnetic pulse.Key technologies such as mechanism analysis of electromagnetic pulse coupling damage, computer electromagnetic pulse protection and simulation modeling of integrated electromagnetic pulse protection of vehicle-mounted information system have been broken through successively.Several patents have been obtained, such as "a transient electromagnetic pulse protection circuit for computer display interface" and "an electromagnetic pulse protection electromagnetic energy adaptive surface for communication system". Aiming at nuclear electromagnetic pulse with high field intensity, short rise time, wide spectrum, wide coverage area and strong destructive power,The coupling simulation model of interconnection cable is established.A variety of HEMP/EMI combination protective filters are designed, and the hierarchical protective schemes for complex systems are designed innovatively.

At the same time, in order to meet the verification requirements of electromagnetic pulse protection design, I based onGJB151A/B（RS105）It is required to establish the nuclear electromagnetic pulse test environment, which has the nuclear electromagnetic pulse irradiation test capability of computer, sensor and other general electronic equipment. On this basis, in order to improve the capacity of equipment and port electromagnetic pulse protection efficiency evaluation, the advanced electromagnetic pulse injection test conditions in China were established based on the mil-std-188-125-2 standard, and the efficiency evaluation of protection module could be carried out, which greatly improved the effectiveness of the electromagnetic pulse test verification
