Spectrum association method for information fusion of underwater platform and weapon

Target association is a crucial technique in information fusion of underwater platform and its weapon sensors, which can generate a more clear situation picture. In this paper, DEMON spectrum analysis was used for target association of two platforms to improve the association performance. Based on the computation of the similarity of DEMON spectrum, an improved cross-correlation method was introduced for spectrum association and the comparision of it with two classical methods was conducted. The simulation results using sea recorded data show that the correlation-based methods can realize the right association between the same targets and have potential application in practical system.
