Measurement method for electromagnetic radiation generated during a high-capacity warhead explosion

Abstract

Abstract To study the impact of explosion electromagnetic radiation on electronic equipment and to improve the anti-interference ability of electronic equipment in an explosion electromagnetic environment, it is necessary to understand the characteristics and laws of explosion electromagnetic radiation. An explosive electromagnetic measurement test is necessary to study this problem. In view of the measurement conditions of the explosive field and the interference factors in the process of a warhead explosion, protection and improvement measures have been proposed. It designs a repeater to compensate for excessive transmission loss of explosive electromagnetic signal. It enhances the anti-interference ability of the measurement system by adopting electromagnetic shielding methods for signal transmission cables. The closed aperture method was used to solve the field line coupling problem in the measurement system. By analyzing the law of seismic wave propagation, equivalent simulation test of instrument vibration and optimization of test point layout, which are conducted to deal with adverse effects such as explosive seismic wave and fragment strike. Finally, an electromagnetic radiation measurement method suitable for the environment of a high-capacity warhead explosive field has been formed.
