Credibility analysis of flight motion table in simulation with frequency domain norm

The importance of credibility evaluation for simulation system in integrated test evaluation technology study of weapon system is addressed. Basic idea and steps of using analytical hierarchy process (AHP) to evaluate the credibility of simulation system are introduced. The vital role of flight motion table as a bottom layer credibility index is analysed. Definition for credibility of flight motion table in simulation (CFMTS) and its measure function are proposed based on similarity theory, the consistency of credibility indexes defined with Euclidean distance in both time domain and frequency domain is proved. Solving method for the lower limit of CFMTS using frequency domain norm is studied while input signal is limited in frequency domain, the relationship between dynamic frequency indexes of flight motion table and CFMTS is given out. Mathematical model for relationship between dynamic frequency indexes of flight motion table and CFMTS is given out. Simulation results illustrate the feasibility of the proposed method.
