Abstract: The hierarchy and the density-based methods are useful system clustering technology in clustering analysis. But those methods are restrictive in many cases. An integrated clustering method was proposed to meet more requests of surface fleet anti-air combat. An attack direction differentiating model was established based on the integrated clustering method. The model can reliably estimate the air attack directions to the surface fleet. It is more helpful to the development of surface fleet C3I system.

Key words: methodology of systematic engineering , integrated clustering method , anti-ship aerial target , attack direction differentiating
