为解决多平台协同数据融合问题,采用基于D-S 证据理论的数据融合方法,分析了该理论在多平台协同数据融合中的应用原理,并将此方法运用于舰船类型的识别。通过 MATLAB 仿真计算对D-S 方法在多平台协同数据融合和单平台数据融合中的应用进行了比较, 验证了该理论在多平台协同数据融合中的有效性和实用性。 Abstract: A method of data fusion based on D-S evidential theory is applied to resolve cooperative multi-platform data fusion problems,The basic theory is analyzied in application and this method is applied to cooperative multi-platform data fusion for target recognition of warship . The application of D-S method in cooperative multi-platform data fusion is compared with that in single platform data fusion by MATLAB simulative computation, the results indicate that the theory is effective and practicable.
