Abstract
Provided are a radar system and a contamination judging method capable of reducing adjustment costs and detecting contamination adhering to a radome with accuracy. The radar system includes an antenna for transmitting a transmission wave in a plurality of different directions and for receiving a reflected wave, a radome for protecting the antenna, and a signal processing unit for calculating a distance to an object based on the transmission wave and the reflected wave, in which the radome has a metallic reflecting section provided in a predetermined direction with respect to the antenna, the signal processing unit has a contamination judging unit which calculates a deviation between a reception level of the reflected wave from the reflecting section in the predetermined direction and a reception level of the reflected wave from directions other than the predetermined direction and judges contamination adhering to the radome based on the deviation.
