  1. The main content and creative work in this dissertation include : ( 1 ) the characteristics of the lfm signals with band width equaling 5mhz, time width in 9 s ~ 42 s, nlfm signals with band width equaling 5mhz, time width in 9 s ~ 21 s are analyzed in frequency domain pulse compression. the corresponding side - lobes suppression filters are designed and optimized

    本文完成的主要工作和創新之處有: （ 1 ）分別完成了對帶寬為5mhz ，時寬在9 s ~ 42 s范圍內lfm信號，帶寬為5mhz ，時寬在9 s ~ 21 s范圍內nflm信號的頻域脈沖壓縮的分析和旁瓣抑制濾波器的設計及優化。
  2. For slow targets whose doppler frequencies fall into clutter doppler band, the performance of frequency domain one - dimension filtering is seriously degraded. in an airborne radar, there is interdependence between the clutter doppler frequency and spatial position. space - time adaptive processing ( stap ) utilizes this interdependence to suppress clutter and get perfect main - lobe and side - lobe clutter suppression

    空時自適應處理利用機載雷達地雜波多普勒頻率與地雜波空間位置的耦合性，根據目標和雜波在空間-多普勒頻域二維空間分佈上的差別對雜波進行抑制。
  3. Because of the importance of the phase modulator in the detection procedure in resonator fiber gyro, this thesis analyses the band side frequency caused by the phase modulation, proposing the methods how to eliminate the band side frequency effect and how to make use of the band side frequency

    由於線性相位調制器在諧振式光纖陀螺的檢測過程中起到重要的作用，本文分析了由於相位調制器調制問題引入的邊帶頻率效應，提出了消除邊帶頻率和如何利用邊帶頻率的方法。
  4. The essential requirements for the frequency synthesizer are : 1 ). low side band power 2 ). high hopping speed 3 ). short convergence time direct digital synthesis technology has the advantages of low cost, low power consumption, high frequency discrimination and short switching time

    直接數字合成技術dds具有低成本、低功耗、高解析度和快速轉換時間等優點，是實現快速跳頻的一個關鍵技術。本文討論了如何實現高速的跳頻系統。
  5. We believe that the improvement of the frequency response is due to a two - mode beat that includes the main mode of the slave laser and the master laser mode, which coincides with the side band of the slave laser

    激光器頻率響應的改善可以用兩個模式的拍頻來解釋，一個模式是從激光器的主模，另一個是主激光器的模式，該模式與從激光器的邊帶重合。
