Open Architecture: Trend of Torpedo and Unmanned

An open architecture method for digital advanced signalprocessing homing head (DasHH) in the torpedo project is described. The relevant delivery rapid sonar COTS insertion (DeRSCI) and acoustic rapid COTS insertion (ARCI) in the open sonar system project are introduced briefly. And the issues of open architecture applied in torpedo and UUV design, including independency of platform, functional modularity, common software tools, independency of data set, application of component technology, the relation between modularity and integration, are discussed. It is pointed out that independent software and data are necessary, common software tools should be adopted within underwater weapon domain, functional modularity level should be designed properly to make balance between openness and management efficiency, focus of integration is information synthesis, and integration design shouldn′t affect the relative independency of key subsystem and functional components
