| 摘要: |
| 针对无线通信条件下数据链网络性能测试和评估难题，设计了数据链网络性能评估方法。首先，采集数据链的记录数据；然后，通过对战术数据系统（Tactical Data System,TDS）数据的消息协议解析，按照数据链消息标准格式化TDS数据，提取时间、消息类型、数据链平台和收发消息四维变量；最后，结合集合映射理论，分析通信网络连通性，生成连通性评估报告和战术消息时序图。基于数据链网络实际业务数据，分析了测试样本经过传输造成的丢包、误码和时延抖动等影响，验证了多源融合方法的可行性和有效性。 |

| Abstract: |
| To solve the problem of data link network performance test and evaluation under wireless communication,a data link network performance evaluation method is designed.First,the recorded data of the data link is collected,and then the tactical data system(TDS) data is formatted according to the standard of the data link message by parsing the message protocol of the TDS data.Finally,the connectivity evaluation report and the tactical message sequence diagram are generated by analyzing the connectivity of communication network based on the set mapping theory.Based on the real data of data link network,the influence of packet loss,bit error rate and delay jitter caused by test sample transmission is analyzed,and the feasibility and effectiveness of the multi-source fusion method is verified. |
| Key words: tactical data system network performance evaluation multi-source fusion set mapping tactical message timing |
