Abstract: In a radar assembly, a first dielectric member includes a dielectric outermost structural member of a vehicle. A radar device includes an antenna module, and a substantially tubular or domed radome. The radome includes a transmissive portion, and is disposed to cover the antenna module such that the transmitted radar wave passes through the transmissive portion. The transmissive portion is disposed behind the back surface of the first dielectric member with space thereto. A second dielectric member includes at least the transmissive portion, and is disposed to face the first dielectric member. A frequency-selective substrate passes a radar wave within a frequency band therethrough, and block radar waves outside the frequency band. The frequency-selective substrate is disposed such that its first surface is directly abutted onto the first dielectric member, and its second surface is directly abutted onto the second dielectric member to constitute a sandwich structure.

Abstract: In an abnormality detection device for detecting whether there is an abnormality in either of an optical sensor and a camera that are used to detect objects around a vehicle, a correlation value calculation unit calculates a correlation value between at least one of a reflection intensity image that is detected by the optical sensor emitting light toward surroundings of the vehicle and then receiving reflected light of emitted light and a background light image that is detected by the optical sensor receiving light from the surroundings of the vehicle while the optical sensor is emitting no light, and a captured image of the surroundings from the camera. An abnormality determination unit is configured to, in response to the correlation value calculated by the correlation value calculation unit being out of a predefined range, determine that there is an abnormality in either of the optical sensor and the camera.
