The radar sensor includes an RF board with at least one antenna and a support bracket configured to secure the detection system to the vehicle. The support bracket has sloped walls forming a radiation aperture between the RF board and the environment. The sloped walls have distal ends distal to the radar sensor. A plurality of sloped flaps extend from the distal ends and slope inwardly from the distal ends towards the boresight axis to intercept radiation within the radiation aperture. ## Claims ### Claim 1 An assembly for a detection system for a vehicle in an environment comprising: a radar sensor positioned around a central boresight axis, the radar sensor comprising an RF board with at least one antenna; and a support bracket configured to secure the detection system to the vehicle, the support bracket comprising: sloped walls forming a radiation aperture between the RF board and the environment, the sloped walls including distal ends distal to the radar sensor; and a plurality of sloped flaps extending from the distal ends and sloping inwardly from the distal ends towards the boresight axis to intercept radiation within the radiation aperture, the sloped flaps forming a functional aperture that is smaller than the radiation aperture, wherein the detection system detects objects within a field of view defined by the functional aperture. ### Claim 2 (depends on 1) The assembly of claim 1, wherein an exterior layer of the support bracket is a metal material and an interior layer of the support bracket is an RF absorbent. ### Claim 3 (depends on 2) The assembly of claim 2, wherein the RF absorbent is absorbent plastic. ### Claim 4 (depends on 3) The assembly of claim 3, wherein the thickness of the absorbent plastic corresponds to an odd number of quarter wavelengths in the absorbent plastic. ### Claim 5 (depends on 1) The assembly of claim 1, wherein the sloped flaps are at an angle of 90 degrees to the sloped walls. ### Claim 6 (depends on 1) The assembly of claim 1, wherein the sloped flaps are angled such that radiation from the RF board contacts the sloped flaps at an angle substantially orthogonal to the sloped flaps. ### Claim 7 (depends on 1) The assembly of claim 1 wherein the sloped flaps are angled to maintain an angle of incident with the RF board of less than 30 degrees. ### Claim 8 (depends on 7) The assembly of claim 7, wherein the field of view is +/−75 degrees around the boresight axis. ### Claim 9 An assembly for a detection system for a vehicle in an environment comprising: a radar sensor positioned around a central boresight axis, the radar sensor comprising an RF board with at least one antenna; and a support bracket configured to secure the detection system to the vehicle, the support bracket having sloped walls forming a radiation aperture between the RF board and the environment, the sloped walls including distal ends distal to the radar sensor and proximate ends proximate to the radar sensor, wherein: the sloped walls are configured to attach sloped flaps between the proximate and distal ends such that the sloped flaps extend inwardly from the distal ends towards the boresight axis to intercept radiation within the radiation aperture and form a functional aperture, the functional aperture smaller than the radiation aperture; and the detection system is configured to detect objects within a field of view defined by the functional aperture. ### Claim 10 (depends on 9) The assembly of claim 9, further comprising a plurality of channels defined by the sloped walls between the proximate and distal ends, each channel configured to receive a sloped flap and maintain the flap at an angle with respect to the sloped wall such that the sloped flap extends inwardly towards the boresight axis. ### Claim 11 (depends on 10) The assembly of claim 10, further comprising a sloped flap removably secured within each of the channels. ### Claim 12 (depends on 9) The assembly of claim 9, wherein the support bracket and the sloped flaps are formed from two layers comprising: a metal exterior layer; and an absorbent interior layer. ### Claim 13 (depends on 12) The assembly of claim 12, wherein the thickness of the absorbent interior layer corresponds to an odd number of quarter wavelengths in the absorbent interior layer. ### Claim 14 An assembly for a detection system for a vehicle in an environment comprising: a support bracket configured to secure the detection system to the vehicle, the support bracket having sloped walls forming a radiation aperture between a cavity for an RF board and the environment, the sloped walls having distal ends distal to the cavity; and a plurality of sloped flaps extending from the distal ends and sloping inwardly from the distal ends towards a boresight axis, the sloped flaps forming a functional aperture that is smaller than the radiation aperture, wherein the detection system detects objects within a field of view defined by the functional aperture. ### Claim 15 (depends on 14) The assembly of claim 14, wherein: the detection system detects objects within a field of view defined by the functional aperture; and the sloped flaps terminate at a position to form the functional aperture. ### Claim 16 (depends on 15) The assembly of claim 15, wherein an exterior layer of the support bracket is a metal material and an interior layer of the support is an absorbent. ### Claim 17 (depends on 15) The assembly of claim 15, wherein the thickness of the absorbent corresponds to an odd number of quarter wavelengths in the absorbent.
