A Technology Optimizing the Information about Shallow Underground Explosion
摘要
Abstract
A technology of shock wave overpressure space-time field reconstruction about underground explosion was put forward,based on the theory of seismic tomography. In order to improve the underground explosion field tomo-graphy information effectively,the paper optimized imaging information from two aspects of model discretization and sensor layout. For discrete model,the irregular grid was adopted according to the attenuation rule of shock wave. For the sensor layout,according to the mathematical underdetermined problem theory and seismic wave propagation law, put forward the index and optimization algorithm for guiding the sensor layout,realize the rational layout of sensors. Simulation results show that, tomography information optimization extraction can maximize the utilization of data, which makes the inversion process is more stable,the inversion error is small.关键词
