Title:
RADAR DEVICE
Document Type and Number:
Japanese Patent JP2022176641
Kind Code:
A
Abstract:
To automatically detect and correct deviation in a short time when there is the deviation in a mounting angle of a radar device.SOLUTION: A side wall parallel to a traveling direction is extracted based on a distance and a relative velocity, which are the positioning results of a radar device, by function fitting processing from a function fitting processing unit (112). Next, a calculation processing unit (114) calculates an angular orientation β of each point extracted as the side wall, based on a vehicle speed and a distance to the side wall calculated during the function fitting. A comparison processing unit (115) compares the calculated angular orientation β and an angular orientation Θ, which is the positioning result, to detect the mounting angular deviation of the radar device, and a correction processing unit (116) corrects the mounting angular deviation.SELECTED DRAWING: Figure 1
