It combines the real echoes with the date simulated using the real airborne sar system parameters to analyze and validate the method. after the combined data are filtered, the improved greatest of cell - average constant - false - alarm - rate ( go - ca - cfar ) is used to judge whether moving target is detected or not. in the following, real moving target is detected and its velocity and position is gained through which it is focused well
將接收的實際場景數據與實際系統參數下模擬的典型數據相結合,分析、驗證了頻域濾波法的性能,並對濾波后的數據採用改進的選大單元平均恆虛警率( go - ca - cfar )方法進行處理,判斷動目標是否存在;然後對實際的動目標進行檢測,準確的估計出目標速度及位置並對目標重新聚焦成像,接下來將聚焦的動目標圖像和常規sar圖像迭加,同時得到了回到真實位置的動目標聚焦圖像和實際場景sar圖像。( 4 ) to determine liquefaction potential in site, several viable approaches are used, and these are ( 1 ) the standard penetration test ( spt ), ( 2 ) measurement of in - situ shear wave velocity ( vs ), and ( 3 ) use of test data and seed & idriss method. considering the non - linear of the soil, we calculate the earthquake response of the soil with the hardin - drnevich model and the finite element method. finally, we estimate the liquefaction capability of the site during earthquake in xuzhou, jiangsu province
中國地展局工程力學研究所碩士學位論文川採用《建築抗震設計規范》 ( gb50on一2001 )基於標準貫入試驗的判別法、基於場地剪切波速的液化判別方法和seed一idriss簡化法對可液化場地進行了液化判別;考慮土的非線性,採用等效線性化模型,利用有限元方法進行了場地的地震反應分析;並對滬蓉高速鐵路徐州段可液化場地的地震液化性能做出了綜合評價。The criterion to judge the relaxation depth of rock mass of excavation slope is defined by analyzing data of sonic wave speed and field investigation, and the distributing law of various weathered degree fossil weathered rock on slope of are educed. the mechanics parameters of relaxed rock mass are studied by using relational expression between mechanics parameters and value of sonic wave speed, which provide convenience for the study of mechanics parameters of rock mass in different state
在此基礎上,利用現場調查和實測波速資料,制定了邊坡開挖巖體鬆弛帶深度的判定標準,從而分析得出了各風化程度古風化巖邊坡的鬆弛帶分佈規律,並採用波速與巖體力學參數的相關式對鬆弛帶巖體的力學參數進行了研究,為研究不同狀態下巖體的工程特性提供了方便。
