Abstract
A radar system detects an object using radar waves and includes an antenna surface and a cover part. The antenna surface is provided with at least one array antenna arranged on a collinear arrangement straight line. The cover part covers the front of an antenna of the array antenna, where the front of the antenna is the side away from which radar waves are radiated with respect to the antenna surface as a boundary. The at least one array antenna is provided with at least one unit antenna where a plurality of antenna elements that radiate radar waves of the same phase are arranged in the same direction as the arrangement straight line. The unit antenna is arranged in a direction perpendicular to the arrangement straight line along the antenna surface. The cover part is configured such that the incidence angle of the radar waves is equal to or less than a Brewster angle.
