Abstract: In view of the shortcomings of communication capabilities under the coordinated operations of manned aircraft and UAVs, the communication capabilities under cooperative combat conditions are analyzed from three aspects, namely, there are barriers to interconnection, the relative surplus of data crowds out data link resources, and the coordination mode is still in the primary level. The concept of data link construction and application is proposed in a targeted manner. Grasp the focus of "digitalization, networking, and intelligence" of the new generation of information technology, and rethink the corresponding solutions in three aspects: data link equipment construction, application and collaboration. It is hoped to provide a reference for the improvement of cooperative combat efficiency of manned aircraft and UAVs and the construction of data link equipment.
