Based on the cloud computing characteristics of distributed parallel processing of massive data,multi-sensor target recognition on the Hadoop platform is put forward, which consists of a plurality of nodes running on computer clusters. Bayesian network structure is established according to target recognition theory. The data obtained by the pre-process of object recognition are fusion-calculated to deduce the target type. The efficiencies of Hadoop clusters under different circumstances are compared. Experimental results show that running multi-sensor information fusion target recognition on cloud computing platform is intuitive and effective, which successfully improves the operational efficiency.
