Research on UAV cluster formation scheme to maintain electromagnetic silence to the greatest extent

This paper discusses how the UAV cluster can maintain a stable formation flight while maintaining electromagnetic silence to reduce external electromagnetic interference. In this paper, a method based on bearing-only passive location is proposed for the most common circular formation and conical formation of UAV as the main research object. The specific technologies are mainly based on Euclidean geometric model positioning method, Kalman filter model and greedy strategy, which significantly reduce the emission of electromagnetic wave signals and improve the positioning accuracy and flight stability between UAVs. This paper discusses the applicability of the method in different formation forms, and provides strategic reference and suggestions for the future application of UAV cluster in complex environment. It also provides a new idea for the more complex formation of UAV cluster in the future, and has important value for improving the concealment and success rate of UAV cluster task execution.
