Abstract
A radar apparatus includes: a transmission processor which transmits first wave signals from inside of the bumper toward outside, the transmission processor being provided inside of the bumper; a reception processor which receives an object-reflected wave signal that is a reflection of the first wave signals by a target in an area around the vehicle, a bumper-reflected wave signal that is a reflection of the first wave signals by the bumper, and a transmission and reception leak signal of the first wave signals and detects the target through the object-reflected wave signal; and a bumper determiner which detects a first reception level of a second wave signal including the bumper-reflected wave signal and the transmission and reception leak signal, compares the first reception level with a threshold, and determines the presence of a bad bumper state in a case where the first reception level is higher than the threshold.
