Naval Situation Assessment Using A Real‐Time Knowledge‐Based System

Abstract

AbstractThis paper analyses the naval situation and threat assessment processes and provides numerical results of an implementation of some situation assessment subfunctions using a real‐time knowledge‐based system called MUSE. First, a short description is given of a MUSE system. Second, a description is given of a MUSE stimulator that generates real‐time air tracks for long range radar, medium‐range radar, fire‐control radar, electronic warfare support measures (ESM), identification friend or foe (IFF), and datalink sensors. Third, a functional diagram of the naval situation and threat assessment processes is provided together with a list of what is believed to be the most important subfunctions of these two processes. The tasks of these subfunctions in the operations room of an anti‐air warfare frigate and the computer modelling of some of these subfunctions using the MUSE knowledge‐based system are then described. Fourth, statistical experiments are described in which three hundred seconds of real‐time air track data is generated on a Sun Sparc 10 workstation by the stimulator and sent through an Ethernet connection to a MUSE situation assessment knowledge‐based system executing on a Sun Sparc 5 workstation. An evaluation of the results obtained from this knowledge‐based system is included in the paper.
