Grant Proposal: Measuring Subsurface Turbulences
Abstract
This proposal seeks funding to develop a multi-modal sensing
platform for the detection, measurement, and visualization of
subsurface turbulences—including structural vibrations, voids, and
hidden dynamic flows—through the integration of radar, spectroscopy,
and acoustic technologies. The resulting system will provide
real-time, high-resolution data in a portable and lightweight
format, bridging the gap between material science, geophysics, and
structural engineering.
1. Background and Rationale
Subsurface dynamics are critical in numerous domains: infrastructure
monitoring, geological exploration, and industrial diagnostics. Yet,
current technologies tend to focus on single modalities—radar,
optical, or acoustic—leading to partial or ambiguous results. The
synergistic fusion of these sensing approaches promises a richer,
more accurate representation of subsurface behavior.
Understanding these hidden turbulences is essential for: - Preventing
infrastructure collapse or failure. - Optimizing geological and
environmental surveys. - Advancing robotics and autonomous exploration
systems.
The proposed project aims to create a multi-sensor framework capable
of detecting, analyzing, and interpreting subsurface phenomena in real
time.
2. Objectives
- Design and prototype a radar-based subsurface detection unit
(RDS) for reflection and vibration mapping. - Develop a spectroscopy module for material characterization and
surface-state analysis. - Implement an acoustic sensing array for vibration transformation
and infrasound capture. - Integrate all modules into a unified, mobile platform.
- Build AI-driven data fusion algorithms for multi-modal
interpretation and turbulence classification. - Validate the prototype through field experiments and laboratory
testing.
3. Methodology
3.1 Radar Subsurface System (RDS)
- Uses electromagnetic reflection principles to map voids, cracks, and
fluid movement. - Employs low-frequency radar emitters and surface detectors for
imaging and depth analysis. - Data will feed into 3D visual modeling algorithms.
3.2 Spectroscopy Module
- Employs light decomposition for analyzing reflected optical spectra.
- Targets material differentiation through spectral signatures.
- Components: high-sensitivity photodiodes, resin/foil layers, and
calibration lenses.
3.3 Acoustic System
- Converts vibrations and infrasound into measurable digital signals.
- Transforms low-frequency turbulence into audible or visual patterns.
- Integrates with the radar unit for synchronized data collection.
3.4 Integration and Data Fusion
- Data from all modules will be processed via a sensor fusion
algorithm. - Real-time visualization tools (2D/3D) will be developed.
- Machine learning techniques will support pattern recognition and
turbulence type classification.
