“…EED, as a miniaturized electromagnetic sensitive element, is not only the "source" for weapon systems to complete the predetermined functions but also the "root" for these systems to have possible accidental ignition, explosion, and other accidents [16][17][18]. Accurate analysis of battlefeld electromagnetic environment, scientifc protection and reinforcement measures, and enhancement of battlefeld survivability of weapon systems are critical to improving combat efectiveness [19][20][21][22]. Terefore, the electromagnetic efect mechanism of the EED should be analyzed to ensure that the weapon system has good combat efectiveness.…”

The electromagnetic radiation sensitivity of the electric explosive device (EED) and its installed use state is closely related to the size of the equipment and radiation field strength constraints. The use of the traditional all-level electromagnetic radiation method for the effect of the actual installed EED test in the electromagnetic environment simulation encountered a technical bottleneck. The microwave band is difficult to effectively assess through the current standing wave distribution and skin effect. The temperature rise of the EED bridge wire has no relationship with the frequency of the electromagnetic wave. In this paper, through the analysis of the electromagnetic effect mechanism of the EED, the coupled power model of electromagnetic irradiation of the EED is obtained, and the relationship between the temperature rise of the bridge wire of the EED and the electric field strength model is established. Under the action of high-frequency continuous waves, the electromagnetic effect of the device is tested to verify the correctness of the mechanism analysis of the electromagnetic effect of the device under the action of continuous waves. The results provide crucial technical support for the electromagnetic protection of the device under the harsh electromagnetic environment of the battlefield.

“…Under the radiation frequency exceeding GHz, the induced current will form a standing wave distribution on the lead wire of the EED, and the current amplitude at different positions will be altered noticeably [31]. As impacted by the measuring probe, bridge wire thickness, and lead electromagnetic induction, the induced current at the bridge wire position is difficult to be accurately measured; besides, under skin effect, the bridge wire resistance and ignition current change with frequency, and its electromagnetic safety cannot be accurately evaluated [32][33][34][35][36]. Wang et al introduced the test method of ignition temperature of EED under electromagnetic pulse in a recently published article [37], but there is no paper published to study the strong field equivalent test method of EED under continuous wave by temperature measurement.…”

The present study proposed the equivalent test method for the strong electromagnetic field radiation of electric explosive devices (EEDs) of the weapon equipment to satisfy the military requirements of the electromagnetic radiation safety test, as well as the evaluation of the electric ignition, the electric initiation ammunition, or missiles. Under stable conditions, the ignition excitation test and the bridge wire temperature increase test were performed to determine the ignition temperature of the EED. As radiated by the strong electromagnetic field, the relationship between the temperature increase of the bridge wire and the electric field intensity of the EED was developed based on the theoretical analysis and the experimental test. Given the ignition temperature of the EED, the radiation field intensity of the EED at 50% ignition was determined. As compared with the 50% ignition field intensity of the EED directly radiated by the strong electromagnetic field, an error less than 1 dB was caused. On that basis, the correctness of the equivalent test method was verified. Accordingly, this method was suggested to act as an effective method and technical means to test and evaluate the electromagnetic radiation safety of ammunition and missiles in unfavorable electromagnetic environments.
