PALSAR雷达影像干涉图中轨道误差去除方法比较与分析
|
摘要
日本宇航局的ALOS/PALSAR雷达影像数据没有相应的精密轨道数据,在利用PALSAR数据进行形变干涉测量时,干涉图中存在的轨道残余相位严重影响形变的精度。去除PALSAR干涉测量中轨道误差影响,常用的方法有二次多项式和附加与高程相关的趋势项的二次多项式方法,利用2011年Tohoku-Oki日本地震的PALSAR数据通过实验对两种方法进行了比较和分析,结果表明,在高程不大、起伏较小区域进行干涉测量时,两种方法去除轨道误差的差别不大。可见,附加与高程相关的趋势项的二次多项式方法适于高程、地形起伏较大地区PALSAR干涉测量的轨道影响去除。
As a result of no providing precise orbit data by Japan Aerospace Exploration Agency( JAXA)for ALOS / PALSAR radar image,the orbit error in the interferogram will reduce the accuracy of the deformation result. The quadratic polynomial method and the quadratic polynomial method with additional trend term related to terrain are common used to remove the orbit error in PALSAR interferogram.Comparison and analysis of these two methods were carried out using the PALSAR data covered 2011Tohoku-Oki earthquake,the results show that in the area of low elevation difference and small ellipsoid height,the difference between these two methods is very small. On the contrary,in the area of large ellipsoid height and high elevation difference,the quadratic polynomial method with additional trend term related to terrain is more efficient to remove the orbit error in PALSAR interferogram.
