The baseline is the key factor in InSAR systems, which will decide the accuracy of the target height calculated from the InSAR. For a two pass InSAR system, the parameter of baseline will change during the flying. And it should be estimated differently. The common way for calculating the Baseline is based on the DEM. Unfortunately, DEM is always difficult to obtain. To use the available data fully, this paper first calculates the baseline by the geometry of orbits.

The baseline is the key factor in InSAR systems, which will decide the accuracy of the target height calculated from the InSAR. For a two pass InSAR system, the parameter of baseline will change during the flying. And it should be estimated differently. The common way for calculating the Baseline is based on the DEM. Unfortunately, DEM is always difficult to obtain. To use the available data fully, this paper first calculates the baseline by the geometry of orbits. Then depending on the key points, e.g. reflection corners, this paper shows an iterative way to refine the baseline. The raw data of Etna in Italy, has been used to verify this algorithm.

研究了对干涉合成孔径雷达系统有重要影响的基线的估计方法。根据多飞干涉合成孔径雷达系统的特性,基线在平台的运动过程中是变化的。为了充分利用现有的资料,首先根据干涉系统的轨道参数计算基线参数,然后利用有限的参考点信息,如角闪烁器,形成迭代算法,从而实现准确估计基线在运动中特征的目的。意大利Etna火山口数据的处理结果验证了本文提出算法的可靠性。

简要分析了日本全国水平的森林公益机能经济价值评价的历史和现状 ,并讨论了将来的发展趋势。日本人对森林公益机能的认识较早 ,频繁的自然灾害和林业经济的不景气是森林公益机能经济价值评价的起因和动机。从 1972年开始的全国森林公益机能的价值评价 ,当时用代替法 (RCM )评价出的金额约为 12 8兆日元 ;1987年单独评价东京圈内的森林价值的结果 ,每公顷森林测算出的价值为 5 0 0万日元 ,如按 5 %的还原率计算 ,其资本还原价高达每公顷 1亿日元。 2 0世纪 80年代还出现了用支付意愿法 (WTP)评价环境财产的事例。至 2 0 0 0年同样用 1972年使用过的代替法 (RCM )重新评价全国森林的结果 ,核算出约 75兆日元的最新数字。但至今为止评价过程中存在问题尚多 ,评价手法上也有局限性 ,其成果仅能为部分林业政策的制定和环境工程的评价起有限的参考作用。指出国际上森林公益机能价值评价今后的动向 ,提出了进一步开展评价理论和方法研究的必要性和重要性 ,并对中国林业可持续发展的启示提出了一些见解
