Research on multi-aircraft cooperative signal-level non-coherent fusion algorithm under data link transmission constraints

To overcome the problem of the current data link transmission capacity being challenging to meet the requirement of signal level cooperative detection, a multi-aircraft cooperative signal level non-coherent fusion algorithm under the data link transmission constraint is carried out. A multi-aircraft cooperative signal-level non-coherent fusion architecture is first presented. Then, the signal-to-noise ratio of signal-level non-coherent fusion is analyzed. Finally, the realization method of the non-coherent fusion accumulation algorithm of data link transmission capacity is given while the signal-to-noise ratio loss is simulated. The research results can provide technical support for realizing airborne radar signal-level collaboration detection technology.
