Abstract:

To improve the reliability and anti-jamming capability of radar countermeasures and reconnaissance systems in complex electromagnetic environments, a comprehensive weight estimation algorithm based on multi-sensor fusion is proposed. Firstly, the original data is estimated by each sensor in batches to obtain the local expectations and variances. Secondly, the quartile dispersion is used to eliminate the abnormal data. Thirdly, the weight of each sensor is ascertained by the measurement operator and the adaptive fusion estimation algorithm for the local estimation results. Finally, the comprehensive weight is used for weighting to obtain the fusion result. Simulation results show that the proposed algorithm can obtain higher fusion accuracy under different conditions, and has better adaptability and accuracy than existing algorithms.

Key words: data fusion, radar countermeasure and reconnaissance, consistency measure, adaptive weighting
