Application of satellite interference imaging technology in building safety monitoring

Abstract

This paper studies the application of the satellite interference multispectral imaging technology in building safety monitoring. The satellite interference multispectral imaging monitoring technology is to measure the radar interference by the observed values of amplitude and phase by repeated orbits or double antenna systems. Compared with the traditional measurement methods, the interferometric SAR satellite imaging technology completely overcomes the defects of low data acquisition ability and poor stability of the system, and has the characteristics of high real-time and large detection range. The use of satellite interference multispectral imaging technology to monitor the safety of buildings is mainly to monitor the size of the building’s settlement and the type of settlement. Combined with the relevant building structural safety regulations, the impact of building settlement on the safety of buildings is inferred. Due to the mature development of D-InSAR technology, the use of ERS data for ground subsidence monitoring can reach an accuracy of 10 mm, which opens up new ideas for building deformation subsidence monitoring.
