Abstract
The present disclosure relates to a radar system featuring a reduced radio cross-section (RCS). This is achieved by providing a radar system comprising one or more antenna structures and a spatially modulated surface structure, wherein the spatially modulated surface structure is configured to generate, from incident radar waves, a first portion of reflected waves and a second portion of reflected waves, wherein the first portion of reflected waves is out of phase in relation to the second portion of reflected waves.
Claims16
A radar system, comprising:
- a structure comprising a first surface and a second surface, the first surface and the second surface being non-overlapping regions of a common plane;
- at least one antenna structure occupying the first surface;
- and
- at least one spatially modulated surface occupying the second surface of the structure,
- wherein the at least one spatially modulated surface is configured to generate, from incident radar waves, a first portion of reflected waves and a second portion of reflected waves, wherein the first portion of reflected waves is out of phase in relation to the second portion of reflected waves,
- wherein the at least one spatially modulated surface comprises a plurality of elements, protruding and/or receding from a baseline surface of the radar system, and each element of the plurality of elements has a height or depth of at least 1 millimeter as measured from the baseline surface, and
- wherein the at least one spatially modulated surface is formed by a manufacturing technique suitable for producing three-dimensional shapes.
