| Abstract_FL | Taking the sixth underground nuclear test of North Korea as an example,based on the ascending and descending ALOS-2 SAR data,firstly,the line-of-sight deformation of the nuclear test site is obtained by D-InSAR technology,and the nuclear explosion parameters are determined by Bayesian inversion method.Then,the POT technology is introduced to measure the azimuth and range deformation of the nuclear test site.Finally,the D-InSAR and POT results are combined to calculate the three-dimensional surface deformation field of the nuclear test site.This study found that the nuclear explosion was located beneath the Wanta Mountain at the Punggye-ri test site in the Democratic People's Republic of Korea.The longitude and latitude of the explosion are 129.0792° east longitude and 41.3026° north latitude,with a depth of approximately 550 m.The nuclear explosion resulted in a horizontal displacement of about 3 m and vertical subsidence of about 1 m.The results indicate that the significance of space-based SAR remote sensing technology,especially long-band SAR,in monitoring underground nuclear test,and it could offer new ideas for underground nuclear test monitoring. |
