基于InSAR地表形变监测的地下强爆炸参数反演
Inversion of parameters for intense underground explosions using surface deformation monitoring with InSAR
摘要
Abstract
Conducting intense underground explosion tests is crucial for countries to develop,test,and evaluate strategic weapons.The resulting parameters are essential for evaluating weap-on capabilities and ensuring national security.In this study,the surface deformation of the target area was monitored using DS-InSAR technology,applying 48 scenes of ERS-1/2 data collected from 1992 to 2001.Then,the Bayesian inversion framework was employed,proving effective in determining the parameters of underground intense explosions using the finite prolate spheroid model and the point compound dislocation model(pCDM).Finally,the accuracy and reliability of both models were analyzed and compared.The results indicate that DS-InSAR technology could effectively detect surface deformation resulting from intense underground explosions.The single-and dual-source finite prolate spheroid models,as well as the pCDM,provided a good fit to the InSAR observations,with the latter offering a superior fit.The results also demonstrate that pa-rameter inversion of geological models based on InSAR data can provide valuable technical sup-port for the study of underground intense explosion tests.关键词
