  1. Compared with current instruments, the setup can decrease disturbance of disorder radiation by using double layer refractive index sample matching vessel, and it can increase collecting and transmitting efficiency of radiation by adopting single mode fiber with gradient refractive index lens. with a low power laser, the sample has a low scathe, and the laser and the measurement system can be integrated conveniently

    與現有的同類型儀器相比,該儀器採用雙層折率樣品匹配池減少了雜光的;採用帶梯度折率透鏡的單模光纖接收、傳輸提高了光的收集傳輸效率;用低強度的激光避免了對樣品的輻損傷,同時可以使激光器和系統集成在一起,整個系統小型實用。
  2. Some valuable conclusions are summarized by theoretical analysis and simulation experiments : from the side of signal processing, pulse jamming can be deleted by the method of time - domain sliding window accumulation and can be restored by interpolative prediction. ; gauss white nose can be attenuated while jamming disperse point - target by the method of time - frequency analysis in time - frequency domain. ; radio frequency noise jamming can be deleted by the method of average range frequency spectrum and notching in frequency domain

    通過大量的理論分析和模擬實驗,得到了一批具有一定價值的結論:從處理的角度出發,對于脈沖式,能夠運用時域滑動窗口積累的方法去掉,並且通過預測插值得到較好的恢復;對于高斯白噪聲,在時頻變換域內應用時頻分析方法可減小其對分點目標的;對于頻噪聲,通過平均距離頻頻法和頻域陷波的方法可以去掉;從改變合成孔徑雷達系統角度出發,類似雙基地雷達能夠避免各種,對發進行調幅,調相以及改變調頻斜率都是較好的抗方法。
  3. The polarimetric information in the target scattering signal has great potential on target detection, enhancement, filtering and recognition. some novel techniques can be proffered for detecting concealed targets, weakening the influences of adverse em environments, confronting active jamming and recognizing targets. basic theory of radar polarization is studied firstly

    雷達目標中的極化息在目標檢測、增強、濾波及識別中有著巨大的應用潛力,為雷達系統在反隱身、削弱惡劣電磁環境的影響、對抗有源和識別目標等方面提供了新的技術途徑。
