In this paper,an adaptive centroid processing algorithm for plot from a multi-radar network was pro-posed,addressing the issue that the detection information of the same target obtained by multiple radars under a networked condition cannot be effectively centroid.Utilizing the redundant characteristics of one-time plot and measurement accuracy matrix,one-time plot fusion from different radar processing stages for the same target were realized at the fusion center.Simulation results showed that this algorithm can effectively improve the positioning accuracy and confidence level of the fused plot,demonstrating high engineering application value.
