| 摘要 |
A passive electromagnetic wave reflector for measuring, from a satellite, local strain in a structure located on the Earth's surface, characterized in that it comprises a substantially vertical, relative to the Earth's surface, planar element, the planar element having a rectilinear side making contact with the structure the strain of which is to be measured, said element being aligned with the axis of the Earth's poles, and, fixed to the planar element, a mechanical structure having a first part located on a first side of the planar element and a second part located on a second side of the planar element, opposite the first side, the mechanical structure forming a rectilinear edge that, in combination with the rectilinear side of the planar element, forms a means for holding in position the reflector on the structure the strain of which is to be measured.
