Research on Determining the Index Weight of DS/FH TTC Anti-jamming Effectiveness Evaluation based on Entropy Method

摘要

Anti-jamming effectiveness evaluation refers to measure and evaluate the DS/FH TT&C performance which is affected by the jamming environment, is an important way to assess anti-jamming performance and optimize TT&C system. Scientific and completed index weight is the key on reasonable and believable of assessment result. An improved algorithm is proposed to solve the problem that weight change is big when entropy tends to 1 and weight is little when entropy tends to 0, objective weight is settled by studying the change under different jamming signal ratio.
