Abstract

This paper proposes a methodology for predicting the electromagnetic compatibility of technical objects under the complex influence of radio transmitter antenna emissions. The main feature of the methodology is its ability to comprehensively account for the simultaneous influence of emissions from multiple radio transmitter antenna systems. The methodology defines the main stages, tasks, and approaches for investigating the influence of radio transmitter antennas on the onboard equipment of technical objects. The operation of such objects is characterized by the emission of electromagnetic fields generated by antennas and, consequently, the generation of electromagnetic interference in the circuits of communication cable lines, which affect the corresponding ports of the onboard equipment. A practical example of applying the methodology for predicting the electromagnetic compatibility of technical objects under the complex influence of radio transmitter antenna emissions is considered. An unmanned aerial vehicle made of composite material is considered as an example of a technical object. The results of a study of complex electromagnetic interactions under the influence of three antenna systems of electronic means simultaneously are obtained. The calculated levels of electromagnetic interference are compared with the requirements of normative and technical documents, which indicate a potential violation of the technical object's electromagnetic compatibility. Thus, the paper proposes a tool that allows for the early stages of a technical object's design to assess the possibility of its electromagnetic compatibility violation under the simultaneous influence of all of the object's antenna systems.
