基于熵权的DS/FH测控系统抗干扰效能评估指标赋权研究

Research on Index Weight Determination of Anti-jamming Effectiveness Evaluation in DS/FH TT&C System Based on Entropy Weight

DS/FH测控系统的抗干扰效能评估是衡量和评价系统抗干扰性能、促进系统优化完善的重要途径。科学合理的指标权重是效能评估结果合理可信的关键。针对熵权法熵值趋于1时赋权变化较大和趋于0时赋权较小的不足提出一种改进熵权方法,通过分析不同干信比下指标的变化确定指标的客观权重。

Anti-jamming effectiveness evaluation refers to the performance measurement and evaluation of DS/FH TT＆C sys- tem. It is an important way to assess the anti-jamming performance and optimize the TT＆C system. Scientific index weight is the key to the rationality and credibility of assessment result. An improved algorithm is proposed to slove the problems that weight changes greatly when entropy tends to 1 and weight has a small value when entropy tends to 0. The objective weight is finally settled by stud- ying the index change under different jamming signal ratios.
