Abstract
A system for testing vehicular radar is described. The system include a free-space polarization adapter (FSPA) configured to alter a first polarization state of electromagnetic waves from a radar device under test (DUT) to a second polarization state, which is different than the first polarization state; and a re-illuminator adapted to receive the electromagnetic waves having the second polarization state from the FSPA.
Claims13
A free-space polarization adapter (FSPA) configured to alter a first polarization state of electromagnetic waves to a second polarization state, which is different than the first polarization state, the FSPA comprising:
- a stack of spacer layers disposed over one another;
- a space in between each of the spacer layers;
- a support membrane extending across each of the spaces;
- and
- sets of wires disposed over the each of the support membranes, with one set of wires disposed in each space, wherein each set of wires is adapted to alter a linear polarization state of electromagnetic waves to another linear polarization state.
A free-space polarization adapter (FSPA), comprising:
- a curtain strip comprising a plurality of elements adapted to alter a first linear polarization state of electromagnetic waves to a second linear polarization state that is different than the first linear polarization state, wherein each of the plurality of elements comprises:
- a stack of spacer layers disposed over one another;
- a space between each of the spacer layers;
- a support membrane extending across each of the spaces;
- and
- sets of wires disposed over the each of the support membranes, with one set of wires disposed in each space, wherein each set of wires is adapted to alter a linear polarization state of electromagnetic waves to another linear polarization state.
