The impact of strong electromagnetic pulses generated in a targeted manner on the process of operation of electronic devices and systems

Abstract

The article presents the basic issues related to the influence of electromagnetic interference on electronic devices used in transport telematics systems. Classification methods for electronic devices and systems in the aspect of interference of strong high frequency (HF) electromagnetic pulses depend on technical parameters of the interfering signals. Generated, strong electromagnetic pulses in this frequency range may be generated purposefully - as intended signals, e.g. to disable electronic devices and systems used in vast transportation areas. Currently, designers and users of electronic devices and systems do not include the possibility of accumulated interference of strong electromagnetic pulses during operation. Current standard and acts do not provide any requirements determining e.g. resistance and susceptibility to high frequency electromagnetic waves. The author recommends including the selected technical solutions and safety indices in operation. Results and calculations presented in the paper prove that it is possible to defend against the threat upon occurrence of strong electromagnetic pulses, already during the design stage of devices and systems.
