  1. Based on the theory of rain - induced rain - induced cross - polarization discrimination ( xpd ), the two - order small argument approximation for rain - induced xpd is developed, and a new model for predicting rain - induced xpd is proposed based on this approximation. the comparisons of this new model with other models and experiments data show that some improvement has been obtained with this model, especially for different polarizations

    基於雨致交叉極化理論，提出了雨致交叉極化的二階小變量近似方法以及新的雨致交叉極化預測模式，與其它模式和實驗數據比較表明，該模式更能反映波的極化特徵，較其它模式有一定的改進。
  2. Because of the structure of the traditional polarization diversity and combining scheme is too complex, after researching the polarization diversity and diversity combining technology, a new structure of receiver is proposed. in this structure the uniform sampling second - order dpll is used to remove the frequency bias after frequency discrimination

    該結構控制較為復雜，為此結合實際項目要求，在研究了極化分集接收關鍵技術的基礎上，提出了一種改進的極化分集接收機結構，即在鑒頻之後利用均勻采樣二階數字鎖相環誤差傳遞函數的高通特性去除各種頻偏分量。
  3. Then, a novel polarization discrimination algorithm of active multi - decoy and radar target is designed and computer simulations indicated that ground - base radar system is possessed of the discriminatory ability of active multi - decoy and radar target

    在此基礎上，設計了有源多假目標的極化鑒別演算法，計算機模擬表明，具有極化測量能力的地基防禦雷達系統具有對有源多假目標進行鑒別的能力。
  4. Cross polarization discrimination

    交叉極化鑒別度
  5. It is manifested by the disordered overspread of the suburbs, the downfall of the central cities, the exacerbation of racial conflicts, and the polarization between the rich and the poor. then the thesis analyzes the direct causes of oversuburbanization : the deep - rooted racial discrimination and the misguided federal housing and transportation policies in the early stage. chapter iv retrospects the train of thought of the federal government on its series of urban policies since the late 1940s to combat oversuburbanization and gives a comment on these measures and explains the fundamental reasons why the federal urban policies always face a paradoxical situation

    第四章回顧了美國聯邦政府自二十世紀四十年代後期著手解決過度郊區化問題的思路和一系列重要的城市政策，並對這些政策做出了評價和分析，指出聯邦政府的城市政策之所以始終處于兩難境地，主要在於聯邦政府對復興中心城市的目的認識不足，未能將窮人的利益考慮在內;其政策制定的出發點是資產階級的整體利益，因此政策實施常常受到來自私有市場的阻撓;同時「州權」和「地方自治」等思想也造成各級政府合作困難。
