Depolarizing radar corner reflector |
摘要 |
A corner radar reflector that backscatters cross-polarized returns from a linearly polarized source is formed by three mutually perpendicular surfaces forming a concave structure. At least one of the surfaces has a depolarizing characteristic. The depolarizing surface is comprised of a grid of thin mutually parallel wires closed spaced. These wires reflect the parallel tangential component of the incident field but do not reflect the orthogonal component. Beneath the wires is a sheet of microwave absorbing material to absorb the energy that was not reflected by the wire grid.
