Multispectral illumination in active millimeter-wave imaging significantly improves concealed object detection by enhancing target contrast and revealing hidden features. Image change detection techniques further refine these W-band images for better object appearance.

Area of Science:

  • Applied Physics
  • Electromagnetics
  • Imaging Science

Background:

  • Active millimeter-wave (MMW) imaging offers superior contrast for concealed object detection compared to passive systems, particularly in indoor settings.
  • The W band is a key frequency range for MMW imaging applications.

Purpose of the Study:

  • To investigate the critical role of multispectral illumination in active MMW imaging for target detectability.
  • To evaluate image change detection techniques for processing multispectral MMW images.

Main Methods:

  • Acquisition of active MMW images of various test objects in the W band using multispectral illumination.
  • Application of image change detection algorithms: image differencing, normalized difference vegetation index (NDVI), and principle component analysis (PCA).
