Base System

• Base System: Gamma Portable Radar Interferometer (GPRI) system (Ku-band; 1.7 cm wavelength)
  
• Portable (and REPEATABLE) tripod or mast-mounted system
• Real aperture radar
  
• Scan rates up to 10 degrees/sec (180 degree scan in 20 sec)
• Range resolution = 0.75 m
• Azimuth resolution ~0.7 m at 100 m;  7 m at 1 km (0.4 ° beam width)
• Sub-mm deformation sensitivity

Additional Capabilities

Horn Antennae (Close Range)

• Some applications (civil engineering) require shorter stand-off
• Horn antennas allow for close up imaging of objects.  <50m
• Custom brackets were machined for Ku Horn antennas.
• 0.75m range resolution
• Ku-band
  

C-band, Quad-Pol

• 5.4cm wavelength
• Quad-pol acquisitions: HH-HV-VH-VV polarizations
• Azimuth Resolution ~20m @ 1km
• Less temporal decorrelation than Ku-band
  
• Appropriate for larger displacements, owing to longer wavelength
