Abstract (en)

[origin: WO2021249817A1] The invention relates to a vehicle assembly (1) for a vehicle (2), said vehicle assembly (1) comprising: - a radar sensor (10) configured to emit/receive radar waves (R1), said radar sensor (10) being placed facing a set of layers (C), and - said set of layers (C) comprising at least two dielectric layers (11, 12), namely a primary layer (11) and a secondary layer (12), separated by a layer of air (13), - characterised in that said layer of air (13) has a thickness (e3) equal to (m3 x (λ/2))/cos(θ3), where θ3 is an angle of incidence of emergent reflected waves (R20) striking said secondary layer (12) and m3=1,…to N, N being an integer, said emergent reflected waves (R20) being derived from radar waves (R1) emitted by said radar sensor (10).
