Method sharing situational awareness information of data link based on airborne data relay using frequency mirroring

摘要

The present invention relates to a method for sharing the situational awareness information of data link based on an airborne data relay using frequency mirroring, and an operating method thereof. It is possible to perform slot allocation and situational awareness information sharing according to various characteristics of a plurality of situational awareness information sharing nodes existing in a data link based on an airborne data relay. It is possible to increase the usability of frames transmitted/received between nodes. Also, since each of the situational awareness information sharing nodes performs resource allocation and information transmission directly without the approval of a coordinator node, the load of the coordinator node is reduced. Platforms with diverse characteristics can efficiently share situational awareness information.
