摘要: Sidelobe suppression is demonstrated for 76-GHz post-wall waveguide fed parallel-plate slot arrays car radar applications. Taylor distribution illumination control successfully confirmed experimentally in the array on waveguide. The amplitude transverse direction controlled by shaping a quasi-TEM mode and that longitudinal realized coupling control, both an oversized Measured sidelobes are below -22 dB one-dimensional (1-D) tapering while those two-dimensional (2-D) -18 dB. gain reduction comparison with uniform less than 1 experiment. All these verify potential of aperture arrays.
