With the three - dimensional ray - tracing program, the simulation of leo - gps occultation is given. the radio path of occultation observation is simulated, and then the excess phase delay is calculated. this work can be used for studying the effects of the neutral atmosphere and ionosphere on the occultation observations and evaluating the performance of the inversion techniques
本文介紹了無線電掩星技術的發展狀況和基本原理,圍繞無線電掩星技術及其應用研究展開諸多研究和探討,主要工作內容如下: 1 、利用全球三維射線追蹤程序,開展leo - gps掩星觀測的模擬研究,以計算掩星觀測時電波傳播路徑、計算大氣引起的附加相位時延等。Moreover, its interior pll circuit substitutes traditional pll. as a result, the presented design not only overcomes some shortcoming of traditional circuit such as tracking speed and accuracy, but also gets rid of response lag time and multi - phase noise. the system design is also important to improve our country ' s fault diagnosis standard
而該系統內部鎖相電路代替了傳統方法中的pll ,因此,提出此系統設計不僅能夠克服基於傳統鎖相環電路的等轉角采樣方法跟蹤精度低、速度慢和使用不便等特點,還能克服電路中的由於不可避免的響應延遲時間所導致的不適合快速的列車運行及過多的相位噪聲問題,對于推動我國鐵路故障在線診斷技術的應用普及具有重要意義。Technology of fine processing was firstly used to make the lsaw biosensor with dual delay linear style. then we developed the dual channels resonance circuit and used the labview software to record and analyze phase / frequency automatically. so the detection system of lsaw biosensor was constructed by combing all these components with network analyzer and computer
方法: 1 .利用精細微加工方法制備雙延遲線型漏聲表面波傳感器,並自行開發研製自激式振蕩電路, labview相位、頻率記錄分析軟體,將它們與網路分析儀、頻譜分析儀及計算機聯用以構建lsaw生物傳感器檢測系統。During the research, finding some important as follow : if wanting to get an ideal linearity of duamoop feedforward system, needing an accurate balance of amplitude and phase, so the attenuation, the delay and the phase in the circuit must be designed accurately
本項研究還發現,雙環前饋系統要獲得理想的線性化效果,還需要精確的幅度和相位平衡,這在電路的設計中表現為要對迴路中的衰減和延遲以及移相環節進行準確的設計。The experimental results show that the effect of ib is much larger than that of the noise on estimating ionospheic delay, and ib can cause ionospheric delay measurements to include systematic errors of the order of several meters. therefore, one must significantly take notice of ib and remove its negative effect, and should not casually consider ib as part of noise whenever gps data are used to fit ionospheric model or to directly calculate ionospheric delay. ( 3 ) stability of ib is studied with a refined method for separating it from ionospheric delay using multi - day gps phase - smoothed code data
算例表明,新方法通過採用平均去噪分離方法后處理相位丞于g陀的電官唇監剝及延遲改正工論與方法的研究平滑測碼數據,求出儀器偏差並對需要實時處理儀器偏差的觀測數據進行預報改止,直接利用觀測值確定電離層延遲量,待估參數少、能消除儀器偏差的大部分影響,具有較好的精度,可作為waas及其他gps網路系統確定電離層延遲的可行的參考方案。分享友人
