摘要
针对机载通信导航识别(Communication,Navigation and Identification,CNI)系统外场检测中广泛存在的检测覆盖率低、性能测试能力不足、测试诊断效率低等问题,提出了一种改进的面向机载CNI系统的外场原位性能检测技术。首先通过资源整合改进原位性能检测架构,在此基础上改进音频信号、灵敏度、频谱分析测试方法,设计了一种复合推理机,最后通过外场实测数据验证了原位性能检测技术的效果提升与诊断的自动化程度提升。
For the problems in the field detection of airborne communication,navigation and identification(CNI)system,such as low test coverage,insufficient performance testing capability,and low diagnosis efficiency,a modified CNI system-oriented field performance detection technology is proposed.Firstly,a performance test architecture is modified through resource integration.Then,analysis and test method of audio signal,sensitivity and spectrum are improved.And a complex inference engine is designed.Finally,through the field test data,the elevation of effect and automation of diagnosis are verified when applying the proposed technology.
