PROBLEM TO BE SOLVED: To provide a radar device and an abnormality determination method with which it is possible to detect abnormality in a bumper that causes the performance degradation of the radar device.SOLUTION: The radar device comprises: a transmission processing unit provided inside a vehicle bumper, for transmitting a transmission wave from the inside of the bumper to the outside; a reception processing unit for receiving an object reflection wave that is the transmission wave reflected by an object around the vehicle, a bumper reflection wave that is the transmission wave reflected by the bumper and a transmission/reception leakage due to the transmission wave; and a bumper determination unit for detecting the first reception level of a first reception wave that includes the bumper reflection wave and the transmission/reception leakage, comparing the first reception level with a threshold, and determining that there is abnormality in the bumper when the first reception level is greater than the threshold.SELECTED DRAWING: Figure 1
【課題】レーダ装置の性能を劣化させる要因となるバンパの異常を検出することができるレーダ装置および異常判定方法を提供する。【解決手段】レーダ装置は、車両のバンパの内側に設けられ、バンパの内側から外側へ送信波を送信する送信処理部と、送信波が車両の周囲の対象物によって反射した物体反射波と、送信波がバンパによって反射したバンパ反射波と、送信波による送受リークを受信し、物体反射波を用いて対象物を検出する受信処理部と、バンパ反射波および送受リークを含む第1受信波の第1受信レベルを検出し、第1受信レベルと閾値とを比較し、第1受信レベルが閾値よりも大きい場合に前記バンパに異常が発生したと判定するバンパ判定部と、を備える。【選択図】図1
