Abstract
An automatic door system includes a double sliding door. The automatic door system includes: one sensor configured to detect a target; and a door opening and closing control unit configured to control opening and closing of the door based on a detection result of the sensor. The sensor includes one or more transmitting elements configured to transmit a frequency modulated continuous wave (FMCW) type transmitted electromagnetic wave, and two or more receiving elements configured to receive a reflected electromagnetic wave obtained by the transmitted electromagnetic wave being reflected by the target. A detection region of the sensor includes, in addition to a region through which the target passes for passing through the door, a region in a vicinity of two door pockets of the door.
