  1. This method offers more precise geometry for spaceborne sar system design and simulation. 3. in the analyzing on the radar doppler properties, under the ellipsoid earth model and ellipse orbit model, considering the earth rotation, the radar doppler properties with different orbit eccentricity are compared, and the fact that orbit eccentricity affects doppler frequency rate is found

    在雷達多普勒特性分析中，論文採用橢球地球模型和橢圓軌道模型，結合地球的自轉，通過不同偏心率下雷達多普勒特性的比較，研究了軌道偏心率對合成孔徑雷達系統設計與模擬軟體研究雷達多普勒調頻斜率的影響。
  2. Discrete approach with 15 ' 15 ' grid is adopted in order to numerically simulate and calculate the gravitational potential field generated by the homogeneous rotation - symmetric ellipsoid, and it is verified that the method, the fictitious compress - recovery and the fictitious downward continuation of the gravitational field, is reliable and valuable at the relative accuracy level higher than 10 ^ ( - 4 )

    摘要採用15 ' 15 '網格離散化手段對均質旋轉對稱橢球體產生的引力位場進行了數值模擬計算，在相對精度優於10 ^ （ - 4 ）的水平上，驗證了引力位虛擬壓縮恢復法以及重力場虛擬向下延拓法的可靠性和有效性。
