传统的多传感器分布式检测反馈方法把融合中心的二元判决送到局部检测器,再利用局部检测器的二元判决形成下一次融合,从而需要双向通信。为了更充分的利用观测信息,降低系统的复杂度,该文提出了一种基于局部检测统计量的多传感器分布式检测反馈方法。新的反馈方案把融合中心的全局统计量重新送到融合中心,与下一步的局部检测统计量一起形成新的全局统计量。并在局部检测器为两个的情况下,分析了新的反馈方案的检测性能并与传统的方案进行了比较。结果表明新的方案使分布式检测性能有明显加强,同时更便于实现。最后给出了实际应用的计算分析方法。
The traditional multi-sensor distributed detection feedback method sends the binary decision of the fusion center to the local detector, and then uses the binary detector of the local detector to form the next fusion, thus requiring bidirectional communication. In order to make full use of observation information and reduce the complexity of the system, a distributed detection feedback method based on local detection statistics is proposed. The new feedback scheme re-sends the fusion center’s global statistics to the fusion center and forms the new global statistics together with the next local detection statistics. In the case of two local detectors, the detection performance of the new feedback scheme is analyzed and compared with the traditional scheme. The results show that the new scheme can significantly improve the performance of distributed detection and make it easier to implement. Finally, the practical application of the calculation and analysis method is given.
