The University of Missouri maintains and operates a portable, ground-based imaging radar as part of a collaboration between the Departments of Civil Engineering, Electrical Engineering, and Geological Sciences. We have procured and enhanced a Gamma Remote Sensing GPRI2 radar system to use for geotechincal, geological, and experimental research.
Our portable, ground-based imaging radar is capable of imaging sub-millimeter deformation of natural and man-made surfaces. In addition to our own research applications, we are open to initiating new collaborations to apply this technology for monitoring ground and structural deformation. For more information, please feel free to contact the PIs listed below.
Base System
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
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
