Corner Reflector prototype testing
20 December 2013
New equipment developed by researchers at Geoscience Australia could pave the way for international satellite operators to independently verify the accuracy of instruments on Synthetic Aperture Radar (SAR) satellites.
The 18 corner reflector prototypes are undergoing a field performance evaluation at a test site north of Canberra prior to being deployed permanently in areas of research interest to the AuScope Australian Geophysical Observing System (AGOS) project.
The geospatial component of AGOS will enable the precise measurement of changes in ground deformation with the corner reflectors supporting studies that use the satellite monitoring technique, synthetic aperture radar interferometry (InSAR). The reflectors will offer a reliable means also to perform ongoing radiometric and geometric measurements for calibration of SAR instruments on satellites.
Geoscience Australia designed and manufactured 18 prototypes of the triangular trihedral corner reflectors in different sizes and material finishes to test and identify their characteristics for InSAR and calibration applications.
