  1. 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。
  2. As the system is regarded as being excited by a constant direct current at the data acquisition point, no complex ac circuit such as filter is required. it can improved the rate of data acquisition and simplify the circuitry of ert system

    由於系統採用了直流脈沖信號作為系統的激勵源,后續的信號處理電路就可以直接獲得測量結果,無需復雜、耗時的濾波電路,這就消除了濾波器這一限制數據採集速度提高的「瓶頸」問題。
