  1. The main content and creative work in this dissertation include : 1. simulate the echoes of the radar, namely produce the lfm signals with band width equaling 5mhz, time width in 9 s ~ 42 s and analyze them in frequency domain pulse compression. at the same time suppress the clutter and indicate targets

    本文完成的主要工作和創新之處有: 1 .通過模擬模擬回波信號，產生了帶寬為5mhz ，時寬在9 s ~ 42 s范圍內帶目標和噪聲雜波的lfm信號，並對其進行了頻域脈沖壓縮的分析，抑制雜波並顯示出目標。
  2. 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。
  3. Because many image information data need to be transmitted and preserved, it is difficult to meet the requests for image information data to be transmitted and preserved by depending only on increasing the width of signal band and the processing speed of computers, we need to use image compression techniques to help to satisfy the requests

    大量的圖像信息需要存儲和傳輸，僅依靠提高通道帶寬和計算機的處理速度，不能滿足人們對圖像信息存儲和傳輸的需要，這就需要結合圖像的壓縮編碼技術來滿足人們的要求。當前圖像壓縮技術在生物醫學應用、無線通信、計算機圖形圖像處理等許多方面有著廣泛的應用。
