High resolution time-series InSAR identification technology of hidden dangers in goaf of closed pit coal mine
In the practical application process,due to the large difference in the geological structure of the hidden danger distribution in the goaf,the traditional InSAR identification technology handles a large amount of phase information in the time-series,and the huge a-mount of information collected in the early detection,resulting in the significant increase in the probability of deviation in the identifica-tion results.In order to solve this problem,the introduction of high resolution-series InSAR recognition technology,mainly through three parts of the establishment of closed pit coal mine goaf hidden danger high resolution numerical model,coherent target high resolution time-series InSAR analysis,characteristic value decomposition phase sequence InSAR recognition,optimize the recognition of global pa-rameters,enhance the processing ability of identifying environmental variables,and achieve the effect of quickly identifying hidden dan-ger features.Improve the processing ability of identifying environmental variables,realize the effect of rapid identification hidden fea-tures.The comparative experiment of simulation data shows that the high resolution time-series InSAR recognition technology has strong identification ability,fast processing speed and accurate identification of hidden dangers.It can solve the shortcomings of the current tra-ditional identification technology,and the future development prospect is broad.
