Electrically Scanned Millimeter Wave Automotive Radar With Wide Detection Region

This paper describes an electrically scanned millimeter wave automotive radar with a wide detection region in a field of view (FoV) and near range. The wide FoV is realized by introducing a beam forming technique to a target search under a low signal-to-noise ratio condition. The short minimum detection range is realized by eliminating a detection error peculiar to frequency-modulated continuous wave radar for a close target. An experimental radar has been developed to confirm the wide detection region. The radar accomplishes the FoV of 40 degrees in azimuth and the minimum detection range of 0.5m.
