InSAR (Interferometric Synthetic Aperture Radar) is a remote sensing technology that uses radar satellites to acquire three-dimensional surface information and deformation data. Its core principle involves analyzing phase differences between two or more radar images of the same area to extract surface elevation or millimeter-level deformation information.
Comprehensive considerations of wavelength characteristics and monitoring objectives:
C-band (Sentinel-1): Suitable for short-cycle deformation monitoring (e.g., earthquakes, urban subsidence) with 5-20m resolution.
L-band (ALOS-2): Strong vegetation penetration capability, ideal for forested areas or long-term crustal movement monitoring.
X-band (TerraSAR-X): 0.25m resolution, optimal for infrastructure millimeter-level monitoring.
Innovative technological breakthroughs: Ensure our technological leadership in providing high-precision monitoring services.
AI long-term research: Leveraging rapid iteration of Chinese AI development, all data processing stages utilize AI and large model capabilities.
Geological hazards: Landslide early warning, co-seismic deformation mapping.
Infrastructure: Thermal expansion monitoring of high-speed rail tunnels, oil/gas field fracturing uplift modeling.
Urban safety: Urban subsidence risk mapping, airport runway crack detection (0.7mm/year accuracy).
Regional regulations: China's Data Security Law requires 20-day security assessment for geological data export. All projects comply with China's technical service export licensing.
Delivery agreement: Original phase data and deformation products belong to clients. Deformation products may be shared for research purposes (subject to client consent and compliance agreements). Final terms subject to formal contracts.
Unmatched precision, comprehensive services, and cost-effectiveness combine to deliver superior monitoring solutions!
