Area of Science:

  • Applied Physics
  • Electromagnetics
  • Signal Processing

Background:

  • Millimeter wave (mmW) and Terahertz (THz) radiation applications are growing.
  • Detecting buried objects, such as land mines and unexploded ordnances, is a critical application.
  • Existing methods may have limitations in sensitivity or specificity for subsurface object identification.

Purpose of the Study:

  • To develop and evaluate a novel active mmW scanning imaging system for detecting buried objects.
  • To utilize hyperspectral imaging in the mmW range for enhanced subsurface analysis.
  • To apply multivariate statistical methods for improved information extraction from mmW images.

Main Methods:

  • Development of an active mmW scanning imaging system operating from 90 to 140 GHz.

  • Application of Principal Component Analysis (PCA), a multivariate statistical technique, for data analysis.

    • Main Results:

    • The system successfully collected hyperspectral mmW images of various buried objects.
    • Principal Component Analysis was effective in extracting relevant information from the complex mmW datasets.
    • Demonstrated potential for differentiating between different objects and experimental conditions based on mmW spectral signatures.

    Conclusions:

    • The developed active mmW scanning imaging system shows promise for buried object detection.
    • Hyperspectral mmW imaging combined with PCA offers a viable approach for subsurface identification.
    • Further research can optimize the system for real-world land mine and unexploded ordnance detection scenarios.
