  1. By using the processing method of sliding time window, the problem of the periodicity range ambiguity is solved. meanwhile, the problem of range ambiguity which is produced because the range of target is biger than the maximum range of radar is also solved by using this method. then, the pulse width parameter which is the most important in the parameters of fmicw is analyzed. the stricter restrict is given to ensure the range spectrum has only one beat frequency after signal processing. at last this thesis introduces the different signal processing methods of fmpcw and fmicw

    同時利用該方法解決了fmpcw信號的由於目標距離超過雷達的最大單值測距范圍而引起的距離模糊問題。然後對fmicw波形參數中最為重要的脈沖寬度進行了分析，給出了更為嚴格的約束條件，保證了信號處理后距離譜峰值的唯一性。最後，分別介紹了fmpcw和fmicw信號的不同處理方式，並對兩者不同的時域濾波性能進行了比較，並對二者的差異進行了分析。
  2. In gan hemt drain pulse current collapse experiments, drain current under pulse condition collapsed about 50 % than direct current condition and the pulse signal frequency affected little on current collapse. when gate voltage is small, the relationship between pulse width and drain current is i0 ( + t / 16 )

    在ganhemt漏極脈沖電流崩塌測試中，發現脈沖條件下漏極電流比直流時減小大約50 % ;脈沖信號頻率對電流崩塌效應影響較小;當柵壓較小時，隨著脈沖寬度的改變漏極電流按i0 （ + t / 16 ）的規律變化。
  3. In gan hemt gate pulse experiments, drain current under pulse conditon collapsed about 47 % than direct current condition and the pulse width affected little on current collapse. the relationship between drain current and pulse frequency is ncoxw [ m + ( n + k ? ) vgs + ( n + k ? ) vgs2 ] ( vgs - vth ) 2 / l

    在ganhemt柵極脈沖電流崩塌測試中，觀察到柵脈沖條件下漏極電流比直流情況下減小了47 % ;隨著信號頻率的改變，漏極電流按ncoxw [ m + （ n + k
  4. At last, in the circumstances of a wide - band radar is used for target detection, the length of received signal is much longer than that of the transmitted pulse signal. because the traditional matched filter collects only a small part of the energy of received signal, it is not good for detection. the generalized matched filter is obtained by improving the traditional matched filter and can collect all energy of received signal, which is good for detection

    最後，在寬帶條件下，雷達發射脈沖信號，雷達的目標回波的時間長度要遠遠大於發射信號的時間長度，傳統的匹配濾波只能收集一部分回波信號的能量，這對于檢測電磁散射比較弱的目標是不利的，而廣義匹配濾波對傳統的匹配濾波進行改進，可以將目標回波的全部能量收集起來以提高檢測性能。
