Classify urban risk points and integrate them with big data such as "three-dimensional geographic information, building intelligent models, satellite radar, positioning video, oblique photography, laser scanning, mobile phone signals, social public opinion", etc., to identify urban hazards and related environments. It is displayed in a real three-dimensional manner to identify various risk sources, risk points, and natural disasters such as typhoons, floods, and geology, and realize query retrieval and statistical analysis.
INSAR technology research and development and application
Introduction to PSP-InSAR principle
◎PSP-InSAR technology is a multi-nested abbreviation of "Synthetic Aperture Radar Interferometry Based on Point-to-Permanent Scatterers";
◎ PS (Permanent Scatterer) refers to various ground targets that have strong backscattering of radar waves and are relatively stable in time sequence, such as the top corners of buildings and structures, bridges, railings, bare rocks, etc. ；
◎ InSAR (Synthetic Aperture Radar Interferometry) refers to a technique that uses phase information in SAR data of different periods in the same area for interferometry.
Quickly respond to urban safety and natural disasters to prevent the settlement, displacement, deformation and remote sensing of urban buildings and infrastructure.
