Title:
RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/244316
Kind Code:
A1
Abstract:
This radar device automatically detects and automatically corrects, in a short time, a deviation when a mounting angle deviates. From a relative speed and a distance that are obtained as a result of performing positioning by the radar device, a lateral wall in parallel to a traveling direction is extracted through a function fitting process by a function fitting processing unit (112). Next, on the basis of a host vehicle speed and a distance to the lateral wall that are calculated during the function fitting, an angle azimuth β of each point extracted as the lateral wall is calculated by a calculation processing unit (114). A comparison processing unit (115) makes a comparison between the calculated angle azimuth β and the angle azimuth Θ obtained as a result of performing positioning, whereby a mounting angle deviation in the radar device is detected and is corrected by a correction processing unit (116).
