Contrast analysis of uniformity of simulation signal based on sequence of fuzzy numbers

The uniformity level of simulation signal is expressed as a fuzzy number by using the fitting method, and its contrast analysis is naturally ascribed to the sequence of fuzzy numbers. Considering the influence of information quantity upon sequence of fuzzy numbers, a sequencing method which ponders the generalized average value, deviation, and information quantity of fuzzy number comprehensively is proposed. Then, a contrast analysis method of uniformity of simulation signal based on the sequence of fuzzy numbers is presented. It is shown by the application of the method in simulation system of target acoustic signal that, the analysis result can provide auxiliary decision-making support for the adjustment and test of signal simulation system.
