摘要

如何有效地改善InSAR的大气效应是进一步提高干涉测量精度的关键问题之一。利用GPS技术校正InSAR大气时延,是利用外部数据校正InSAR大气时延最有效的方法。利用北京和武汉的GPS数据,采用距离幂逆插值和克里格插值方法,研究了不同地形对对流层延迟插值的影响。结果表明,幂次距离反比法与克里格插值法具有相同的效果。武汉和北京对对流层延迟插值的影响不同。武汉地区的插值效应达到毫米级,但与北京地区的插值效应不同。在平坦的乡村可以到毫米,而在山区可以到厘米。为了应用具有GPS天顶对流层延迟的InSAR大气校正,需要进行地形校正进行插值。

The Study about Comparison of Zenith Tropospheric Delay Interpolation Methods Based on Different Terrain
It is one of the key issues to further enhance the accuracy of interferometry that how to effectively improve the atmospheric effects in InSAR. Using GPS technique to correct atmospheric delay of InSAR, it is the most effective method to correct InSAR atmospheric delay with the use of external data. By using the GPS data of Beijing and Wuhan, it is adopted Inverse Distance to a Power and Kriging interpolation methods to study the effect on tropospheric delay interpolation among different terrain. It is concluded that there are the same effect between inverse distance to a Power method and Kriging interpolation method. The effects on tropospheric delay interpolation are different between Wuhan and Beijing. The interpolation effect in Wuhan region amounts to millimeters, while it differs from the effect of Beijing. It can be going to millimeter in the flat country, while it goes to centimeter in mountain area. It should be conducted terrain correction for interpolation in order to apply the atmospheric correction of InSAR with GPS zenith tropospheric delay.
