基于陆探一号卫星升降轨数据和DEM，以2024年1月23日新疆维吾尔自治区阿克苏地区乌什县M_S7.1地震为例，利用二轨合成孔径雷达差分干涉(DInSAR)技术提取乌什县地震升降轨的同震形变场，并与哨兵一号卫星数据提取的结果进行对比分析，验证了陆探一号卫星数据在地震发生前后获取的地球物理场变化信息的准确性与可靠性。结果表明，乌什县地震陆探一号卫星升降轨数据最大视线向抬升量分别为126、138 cm，最大视线向沉降量分别为13、33 cm；以垂直方向形变为主，同震形变场形变趋势与哨兵一号卫星升轨数据基本一致。

Based on the ascending and descending orbit data from the LT-1 satellite and DEM, taking the M_S7.1 earthquake occurred on January23, 2024, in Wushi County, Aksu Prefecture, Xinjiang Uygur Autonomous Region, as a case study, we used the two-pass differential interferometric synthetic aperture radar(DInSAR) technology to extract the co-seismic deformation fields of ascending and descending orbits in Wushi County,and compared with the results derived from Sentinel-1 satellite data, to verify the accuracy and reliability of geophysical field change information obtained by LT-1 satellite data before and after the earthquake. The results indicated that the maximum line-of-sight uplift amounts for the LT-1satellite data during the Wushi County earthquake were 126 cm(ascending orbit) and 138 cm(descending orbit), while the maximum line-of-sight subsidence amounts were 13 cm(ascending orbit) and 33 cm(descending orbit), respectively. The deformation was mainly in the vertical direction, and the trend of co-seismic deformation field was generally consistent with the ascending orbit data from the Sentinel-1 satellite.
