Description

This target group of 40 corner reflectors is a regional-scale geodetic network that has been installed by Geoscience Australia in the Surat Basin, Queensland, Australia. The permanent installation of corner reflectors was completed in November 2014. The network incorporates 65 survey marks and 40 radar corner reflectors to enable the combination of Global Navigation Satellite System measurements with remotely sensed surface deformation maps derived using the Interferometric Synthetic Aperture Radar technique. The combination of these geodetic techniques in this region will bring an enhanced understanding of how resource extraction affects the ground surface. Although their main purpose is for geodetic monitoring, by design the corner reflectors are also able to support ongoing radiometric calibration and geometric validation of X, C and L-band SAR imagery. Please check site Surat Basin 26 to see an image of a typical 1.5 m triangular trihedral corner reflector. Further details about the corner reflector array are given in the following papers:
