  2. Due to the short distance among the planes which fly in a group, the conventional low resolution radar can not distinguish them in both distance and azimuth ? if we use the technology of isar to resolve the difference among doppler frequency of the targets and obtain a fine resolution cross - cross image, we may separate them, but a long time of coherent processing is needed <, for the formation targets, it can be approximately divided to rigid body and nonrigid body, so for the formation targets, that can be regarded as rigid which has a relative position and an identical movement, can be approximately considered as a large target, and be compensated by translational phase with the rule of minimum entropy, but for the most those cannot accord with the approximation of rigid, being the doppler - frequency of the aim is linear changed, by the relax method with short data, increases the resolving performance of multiple target to the aim in the frequency domain, since cross - range resolution is based on the accumulative time, so it is greatly improve the resolution to formation targets by the instant cross - range image which produced by radon - wigner transformation

    低分辨isan成像及干涉技術應用研究一因此直接無法分辨編隊目標的架數,我們借鑒isar的技術,通過較長時間的相干積累,在多普勒頻域上對目標進行分辨。而對于編隊目標,可分為近似剛性的多目標和非剛性的多目標,所以對于可以近似為剛體的編隊目標相對位置固定,運動方式一致,可以近似看作一個大目標,採用最小墑準則對平動相位的進行補償,但是大多數並不滿足剛體近似的編隊目標,由於目標在相干積累時間的多普勒頻率近似呈線性變化,通過對較短數據利用relax的時頻分析方法,提高了頻率域上目標分辨的性能。由於橫向解析度取塊于橫向積累時間,所以利用radnwigner變換得到瞬時的一維橫向距離像大大提高了對編隊目標的分辨,對模擬和實測數據的大量分析結果表明此方法的有效性和可行。

  4. The transformation of the style of a painter inevitably contains a certain dilemma of risk. however, as a painter, he no longer cares about what to paint, but whether to be able to paint continually. “ terracotta warriors in series ” is more of opening a jewel box where a wide range of possibilities is hidden than just a series of integrity and wonderful masterpieces

    一個畫家風格的改變必然蘊含著某種進退失據的風險,但對畫家而言,他在乎的往往不是畫出了什麼,而是能否繼續畫下去, 《兵俑系列》毋寧說是一組完整美妙的作品,不如說是開啟了一個蘊含多種相度可能的寶盒。

    這種新的圖像增強方法包括三個階段,即圖像濾波、模糊增強和灰度級變換,擴大了原始圖像灰度等級的范圍,在保留了原有模糊增強方法和灰度變換優點的同時,規范化了模糊增強環節中灰度隸屬度函數的形式。
  8. Abstract : we conduct a theoretical study on the properties of a bound polaron in a quantum well under an electric field using linear combination operator and unitary transformation methods, which are valid in the whole range of electron - lo phonon coupling. the changing relations between the ground - state energy of the bound polaron in the quantum well and the coulomb bound potential, the electric field strength, and the well width are derived. the numerical results show that the ground - state energy increases with the increase of the electric field strength and the coulomb bound potential and decreases as the well width increases
