DS/FH测控系统抗干扰性能评估方法研究

Evaluation Method for Anti-Jamming Performance of DS/FH TT&C Systems

针对DS/FH(直接序列扩频/跳频扩频)测控系统的抗干扰性能分析问题,提出了一种从效能评估角度出发的分析方法。通过引入层次分析技术,建立了系统抗干扰性能评估结构模型,利用仿真结果确定判断矩阵,解决了层次分析法采用专家系统确定判断矩阵主观性强的弱点,最后通过权向量计算、一致性检测、层次总排序完成了系统设备抗干扰性能评估和优选。分析和仿真结果表明,该评估方法能准确评估不同设备的抗干扰性能,可以有效帮助用户完成设备优选。

A new analysis method is presented from the perspective of effectiveness evaluation for analysis of the anti- jamming performance of DS （Direct Sequence）/FH （Frequency Hopping） TT＆C （Tracking, Telemetry and Com- mand） systems. A structural model is established for evaluation of the anti-jamming performance of TT＆C systems through introduction of hierarchical analysis technology. Judgment matrix is determined with simulation results to o- vercome the drawback of subjectivity of matrix judgment with expert systems in use of hierarchical analysis method. Finally, system evaluation and optimization is carried out through weight vector calculation, consistency checking and hierarchical sorting. Analysis and simulation results show that the evaluation method facilitates accurate evalua- tion of the anti-jamming performance of different equipment and provides effective assistance to selection of equipment.
