Pepeat-pass interferometry with airborne synthetic aperture radar

  • 摘要: 該文描述了中科院電子所機(jī)載L-SAR系統(tǒng)的重復(fù)軌道干涉試驗(yàn),通過對(duì)得到的觀測(cè)數(shù)據(jù)進(jìn)行處理和分析,得到了中國(guó)第一幅與實(shí)際地形圖基本吻合的數(shù)字高程圖,高程精度在10m左右。同時(shí),該文提出一種適用于軌道有夾角的圖像配準(zhǔn)方法,并在處理過程中驗(yàn)證了算法的有效性。
    Abstract: In this paper, the interferomtric experiments on airborne L-SAR system of IECAS is demonstrated. And data obtained from experiments are processed, and Chinese first DEM with repeat-pass airborne SAR, which nearly accords with the real topographic map, is obtained, and its height accuracy is about 10m. A new imaging coregistration method for crossed-orbit is presented and its effectiveness is tested by airborne data.
