According to the Environment Agency Report on the general condition of the land subsidence area in the whole country, the area where 1cm or more foundation of years sank in the Japan whole country is remarkable especially in Chikugo and the Saga plain, and is especially specified to be a 4cm[/(year] or more specification area and which this research makes the amount region of an object of research, and the cause of the land subsidence is reported in connection with water for agricultural use. In such a situation, this research uses a SAR satellite, and adopts the Interferometric Synthetic Aperture Radar(InSAR) called highest sensitivity of several cent meters as the detection method.Furthermore, the 3-dimensional information on the absolute value of land subsidence can be acquired by this InSAR after land subsidence takes place, and taking the difference of 3-dimensional altitude data before and after land subsidence. This processing technology is called as Differential InSAR(DInSAR), which was performed for complex images, and carried out for single look image processing of the day evening[1994-4-29,1994-10-22] of JERS-1/SAR. Furthermore, an interferometric picture, a coherence picture, and DEM image were obtained as a result of analyzing data, being based on land subsidence, which is considered an evidence in the Saga Shiraishi district, though it was weak, interference fringes could be checked Furthermore, for the check, the field survey in the Shiraishi district was carried out again. Moreover, these results are due for the leveling result which here Saga Prefecture performed to also come to hand, to perform comparison with InSAR, and to be released.

根据环境厅关于全国地面沉降地区概况的报告，在日本全国，特别是筑后和佐贺平原，地基年沉降1 cm或以上的面积是显著的，特别规定为4 cm [/（年）]或以上的规格面积，本研究将其作为研究对象的数量区域。据报道，地面沉降的原因与农业用水有关。在这种情况下，本研究利用合成孔径雷达（SAR）卫星，采用最高灵敏度为几厘米的干涉合成孔径雷达（干涉合成孔径雷达）作为探测手段，在地面沉降发生后，利用地面沉降前后三维高程数据的差值，利用该干涉合成孔径雷达获取地面沉降绝对值的三维信息。这种处理技术被称为差分干涉合成孔径雷达（D干涉合成孔径雷达），它是针对复杂图像进行的，也是针对JERS-1/SAR白天/晚上的单视图像进行的[1994-4- 29，1994 -10-22]。此外，根据佐贺白石地区被视为证据的地面沉降，作为数据分析的结果，获得了干涉图像、相干图像和DEM图像，虽然干涉条纹很弱，但可以检查。此外，为了检查，在白石地区再次进行了实地调查。此外，这些结果是由于这里的佐贺县进行的水准测量结果也即将到来，与干涉合成孔径雷达进行比较，并将被发布。
