介紹了一種反對稱漸變波導微帶探針過渡結構，采用高頻仿真軟件HFSS仿真分析了這個波導微帶過渡結構在 W 頻段的特性，并對影響過渡性能的幾個因素進行了敏感性分析，得出了可供工程應用參考的設計曲線。在全波導帶寬內，實現了插入損耗小于0.088 dB，回波損耗大于27 dB。該結構具有寬頻帶、結構簡單和易加工等優點，可廣泛用于毫米波固態電路系統中。
在航電系統維護過程中，為解決定位故障的效率和降低維修成本等問題，提出了基于ICD（Interface Control Document，接口控制文件）的1553B總線的信息監控系統模型。該系統運用數據采集卡對總線中傳輸的信號有無失真、偏差等電氣特性進行檢測，并使用1553B通訊卡通過測控軟件LabWindows/CVI編程與ICD數據庫的動態鏈接，實現總線信息的解析和故障的判斷。與傳統的維護過程相比，這種模型能夠從信號的電氣特性以及信息的解析等全方位的去檢測判斷故障的來源，并且能夠廣泛在其他1553B總線系統內擴展應用。驗證表明該監控系統可以對總線信息進行快速有效地監測分析，能滿足應用需求。
Abstract: In the process of avionics system maintenance， to solve the problems such as improving the efficiency of fast orientation to troubles and reducing maintenance cost， system of 1553B bus information monitor model based on ICD was proposed. The system observed whether the data which transmitted on the bus appear distortion and deviation by using data acquisition card. And using 1553B communication card programming of the measure software LabWindows/CVI and the dynamic linking of ICD database， message analysis and fault estimation could be realized. Compared with traditional maintenance， this model can all-dimensionally detect and analyze the source of faults from both electrical characteristics of the signal and message analysis， and it can be widely applied in the other 1553B system. Experiment shown that this monitor system can effectively detect and analyze the bus message and can meet the application requirements.
