摘要
针对D-InSAR技术二轨法中先差分再解缠和先解缠再差分2种情况,以钱营孜矿区为例,采用ALOSPALSAR数据进行差分处理,并与地面水准观测结果进行比较,最终得出结论:两者所得沉降结果与水准观测结果沉降趋势相同,但先差分再解缠的精度要远高于先解缠再差分的精度。
Aiming at the two kinds of circumstances of first difference then solution bound and the opposite in two rail method, taking Qianyingzi mining area as example, with ALOS PALSAR data difference processing, compared with the ground level observation, finally comes to the conclusion： both of the difference methods have the same tread with the result of the ground level observation, but the accuracy of first difference then solution is far higher than first solution then difference.
