一种测控系统抗干扰性能评估模型

为了对测控通信系统数据传输性能进行客观有效的评估,针对测控系统的测量链路和遥测链路,设计了一种抗干扰性能评估模型。将传输可靠性、频谱效率、功率效率、干扰抑制性能作为抗干扰性能评估指标,在对各评估指标规范化处理的基础上,基于μ律对数压缩方法生成各指标性能和综合性能评价值,并映射成相应的性能评估等级,能够得到测控系统的测量链路和遥测链路中不同的性能指标和总抗干扰性能指标的评估值和评估等级。仿真表明,提出的评估模型可以客观有效地对测控系统的测量链路和遥测链路的抗干扰性能联合进行评估,并通过评估等级直观地反映链路性能的优劣。

An anti-jamming Performance Evaluation Model for TT&C Systems

In order to objectively and effectively evaluate the performance in the data transmission process of a telemetry,tracking and command( TT&C) system,an anti-jamming performance evaluation model is designed for the measurement and telemetry link of TT&C system.The transmission reliability,spectrum efficiency,power efficiency and jamming suppression performance are used as the anti-jamming performance evaluation indicators.Based on the normalization of each evaluation indicator,the performance and comprehensive performance evaluation values of each indicator are generated based on the μ law-logarithmic compression method,and mapped to the corresponding performance evaluation level.The model can give the evaluation values and evaluation levels of different performance indicators and total anti-jamming performance indicators in the measurement and telemetry links of TT&C system.The simulation shows that the evaluation model proposed in this paper can objectively and effectively evaluate the anti-jamming performance of the measurement link and the telemetry link of TT&C system,and also directly reflect the quality of the link performance through the evaluation level.
