    最後，本文針對懸停直升機旋翼回波的時頻域特點，探討了從回波信號中提取旋翼回波最大線速度v和旋翼回波閃爍周期tp的方法，在綜合利用這兩種信息的基礎上完成了彈載高重頻脈沖多普勒體制雷達對懸停直升機回波信號的識別。
  3. In the subsystem of signal processing, digital sidelobe cancell block, digital pulse compress block, adaptive clutter canceller block, doppler filter and constant false alarm rate block are respectively discussed and set up. in signal processing, data in the same coherent processing interval form a matrix, and the data processing was completed based on the matrix. data are processed with the row vector or column vector respectively when needed

    在信號處理分系統中，將脈沖壓縮得到的數據在各個相干處理區間進行處理，將一個相干處理區間的數據按照不同的脈沖重復周期和不同的距離單元排列成一個矩陣，當需要實現數字脈沖壓縮時對矩陣的各行（同一個脈沖重復周期的數據）進行處理，當需要實現多普勒濾波時，就對矩陣的各列（同一個距離單元的數據）進行處理。
  4. Based on the importance of pulse / pattern generator, the work of this dissertation comes from the project “ high speed pulse / pattern generator ”, which is taken on by the university of electronic science and technology of china. the dissertation focuses on the process of pulse generating, and its main task is to generate pulse waveforms with adjustable parameters ( including period, pulse delay, pulse width and etc )

    基於研發脈沖/數據發生器的重要性，結合電子科技大學承擔的科研項目「脈沖/數據發生器」 ，本文圍繞脈沖的產生的過程進行展開研究，主要任務是實現具有各種參數（包括周期、脈沖延遲、脈沖寬度等）可調的脈沖數字波形。
  5. Second, a new type character pulse cycle chose method was k value wave - chose way. it broke the traditional idea that only chose one pulse circle wave, in fact, appropriate character circle waves should be the analyzed objects. the chosen standard was according to the k value which was proved to be a valuable parameter of pulse

    其思想突破了傳統思想上只選用一個代表周期波形來分析的局限，可以選取多個有效的周期波形;其方法彌補了常用的基於平均值方法選取代表周期波形的注重一般、忽視特別的思想，採用了被研究證明了的在脈搏信號中有重要綜合價值的生理參數k值來作為選波的依據，使得脈搏信息的揭示全面而細致。
