Abstract:

In this paper, the preliminary knowledge and usage of fuzzy inference systems toolbox for MATALB and basic computing method of threat degree of sea target were introduced, and the simulation of threat degree of sea target using fuzzy inference systems toolbox for MATLAB was given. According to basic requirement of computing of threat degree of sea target and method of constructing of fuzzy inference system, the membership function of each variable and fuzzy rules of system was established. The result of simulation indicated that the membership function and fuzzy rules could easily be done using fuzzy inference systems toolbox for MATLAB, and the effect of input variable to output variable is very intuitionistic too.
