Passive corner reflectors, made typically of metal plates, are widely used as point targets in synthetic aperture radar (SAR) and SAR interferometry (InSAR) applications. Drawbacks of such corner reflectors include: (i) high cost, especially when many reflectors are required for monitoring purposes; (ii) creation of localised ground motion in soft or unstable soils; and (iii) attractiveness for thieves. We tested several lower-cost and lighter weight materials for making corner reflectors. A cub
