“…EMI will cause the non-linear distortion of airborne receivers, which will lead to the interruption of data link communication and seriously threaten the battlefield survival of UAVs. Jiao Yanwei [17] used cloud model method to study the comprehensive effectiveness of UAV in complex electromagnetic environment, and established the effectiveness evaluation index system of hierarchical structure of UAV in complex electromagnetic environment. Liu Ruiqi et al [18] deduced the inequality of tracking interference hyperboloid and limited power interference range from the time domain and power condition of tracking interference, determined the effective interference range under different parameters, and proposed a reasonable jamming start-up strategy.…”

The electromagnetic environment of UAV system was studied, and three key elements of electromagnetic interference (EMI) are analyzed. The research status of electromagnetic characteristics of UAV system at home and abroad was summarized from numerical simulation of EMI, experimental test of EMI and design of electromagnetic compatibility (EMC). The main contents include the research on electromagnetic characteristics of airborne antenna, EMI of data link and its mechanism, electromagnetic characteristics of internal cables, electromagnetic radiation test, electromagnetic conduction test, system-level EMC design, etc. The key technical challenges faced by the research on EMC of unmanned aerial vehicles at home and abroad are pointed out. Research on Electromagnetic EnvironmentWhen UAV is flying, it is not only affected by electromagnetic environment caused by radiation of internal equipment, but also by external electromagnetic environment such as lightning, interference station, nuclear electromagnetic pulse and so on. The radio frequency radiation overlaps in space, time, frequency and energy with the different working environment of UAV. If these interference cannot be prevented reasonably, the performance of airborne equipment will be greatly affected [1,2]. These EMI will not only interfere with the normal work of the UAV electronic system, but also destroy the key components of the electronic equipment, resulting in the failure of the instrumentation or control system, which directly threatens flight safety.Electromagnetic environment refers to the sum of power or field interference in different frequency range and the kinds and states of various interference sources when the UAV is performing its mission [3]. The external electromagnetic environment of UAV can be divided into natural electromagnetic environment and man-made electromagnetic environment. Natural electromagnetic environment exists objectively, including lightning, static electricity and earth electromagnetic field; human-made electromagnetic environment is formed by human activities, including electromagnetic wave emission, receiving activities caused by wireless communication and additional electromagnetic fields generated by these activities. The internal electromagnetic environment of UAV mainly includes antenna feed system, electromechanical system and circuit system.
