A weighted fusion method based on robust error scale estimation
In view of the interference of complex electromagnetic environment and the non-robustness of traditional method in the weighted fusion of multi-source electronic measurement data, with robust statistics theory as a guide, this paper proposed a robust filter method based on real-time median estimation, and applied the filter residual error scale to the dynamic fusion weights calculation under the optimal weight assignment principle, then obtained a new distributed robust weighted fusion method. The results of the test with typical measured data showed that the methods proposed were effective and robust in practical engineering application.
