Satoru Arita

A vehicular radar device detects an object within a detection area on the basis of detection data having a reception intensity exceeding a predefined threshold. The detection data is contained in reflected-wave data on waves irradiated into the detection area outward of a vehicle provided with the vehicular radar device. The device is capable of varying a direction or/and a range of the detection area in a vertical direction, and setting, during a normal time, the direction or/and the range of the detection area in the vertical direction to a normal state in which the object is correctly detected, and performing a detection operation in the normal state.

Vehicular radar device

A vehicular radar device capable of accurately detecting rain or the like or a road surface by discriminating between the rain or the like or the road surface and others. The vehicular radar device has a control circuit which performs a detection operation in an up state in which the visual field of the radar is shifted comparatively upwardly in the vertical direction so that the road surface is not detected, and determines that, from among detection data obtained during the up state, detection data which does not vary in reception intensity nor in reception delay time (distance data) for a predefined time is detection data relative to rain or the like.
