Design, deployment, and localization of bidirectional corner reflectors for TerraSAR-X

This paper reports on the use of a distinctively designed and deployed bi-directional trihedral corner reflector pair. The reflector is adjustable having two degrees of freedom in azimuth and elevation directions with one end of the pair firmly attached together. One side of the pair is visible to the satellite in its ascending orbital pass while other side is visible in the descending pass. Lightweight Aluminum and assemble-able design makes it easy to be manufactured and transported to the rooftops. Moreover, the design is simulated using a general purpose electromagnetic simulation software, CST and the Radar Cross Section is measured and verified. The installed reflectors were identified and localized in the acquired TerraSAR-X image data.
