What could a RF-THz imager allow that can’t be done now?

• Suicide bomber detection: working at a safe/covert distance, check for contrast between skin, explosives, concealed weapons using non-ionizing, non-harmful radiation
• Could use a 33 cm aperture (300 GHz) or 20 cm aperture (500 GHz) to resolve:
  • 2.5 cm features @ 8 m standoff
  • 6 cm features @ 20 m standoff
  • 15 cm features @ 50 m standoff
• IED detection combined with ground-penetrating radar (GPR), particularly with polarization sensitivity
• Locating an enemy hiding in a building
• Standoff surveillance of a facility
• Crisis response, locating hostages
• Search and Rescue: Post-disaster, locating hurricane, earthquake, flooding, bomb victims
• Port security: Scanning of cargo containers
• Detect explosives on personnel (counter suicide bombers) or in concrete (IEDs)
• Border security, detect people hiding in strange places in vehicles (under seats, dashboard, etc.)
• Harsh weather navigation
• Biometric/biological, chemical sensing
