  1. To improve this ability, a higher cross - range resolution is needed. an inverse synthetic aperture radar ( isar ) achieves high resolution in the cross - range dimension by taking advantage of the motion between radar and targets to synthesize the effect of a larger antenna aperture

    逆合成孔徑雷達( inversesyntheticapertureradar ,簡稱isar )信號處理對接收到的運動目標的回波信號進行相干處理,等價成一個大口徑天線,很大程度上提高了方位向距離分辨力。
  2. Based on the doppler effect and pulse coherence technique, synthetic aperture radar ( sar ) breaks through the azimuth resolution limitation imposed by real aperture antenna. in combination with the pulse compression technique, two - dimensional high resolution imagery to distant targets can be realized

    合成孔徑雷達( sar )利用以多普勒頻移理論和脈沖相參為基礎的合成孔徑技術,突破了實孔徑天線對方位向分辨力的限制,與脈沖壓縮技術相結合,實現了遠距離目標的二維高分辨成像。
  3. In airborne synthetic aperture radar ( sar ), antenna stabilization platform is used to isolate antenna pointing, which is stabilized through controlling the platform axis ' rotation, from the vehicle ' s varying attitude and dynamical vibration

    摘要機載合成孔徑雷達中,天線穩定平臺用於隔離載機的姿態變化和機械振動對天線指向的影響,並通過伺服系統控制平臺支承軸的轉動穩定波束指向。
  4. 4. the motion compensation problem, which is one of the important problems in synthetic aperture radar is discussed in this paper, the method to install three accelerometers in the center of the antenna is discussed in detail

    (四)討論sar運動補償的問題,這是合成孔徑雷達研究中的一個主要問題,本文主要論證了將三個加速度計安裝于天線相位中心處的方案。
  5. Spotlight synthetic aperture radar can efficiently obtain an image with very high azimuth resolution, since its antenna illuminate the fixed target on the ground. bistatic radar is not a new concept and its fundamental principles have been known and demonstrated many years before the development of operational monostatic radar

    由於其天線波束始終照射同一目標場景,因此可獲得更大的方位多普勒帶寬和更高的方位分辨力,但實際上由於受數據處理條件、載體運動誤差等因素的影響,方位解析度的提高是有限的。
