  • Off-axis angle estimation method and apparatus using the same
    Patent number: 7545313
    Abstract: Without using a traveling velocity of a vehicular object mounted with a radar device, an off-axis angle which is an offset angle between a reference direction of the radar device and a traveling direction of the vehicular object is estimated.
    Type: Grant
    Filed: November 12, 2004
    Date of Patent: June 9, 2009
    Assignee: Mitsubishi Electric Corporation
    Inventors: Atsushi Okamura, Rokuzou Hara, Toshio Wakayama, Toshiyuki Hirai
  • Radar system
    Patent number: 7443335
    Abstract: To obtain a radar system capable of obtaining an appropriate angular precision by calculating an angle error based on distributions of relative speeds and angles of reflecting points, and of obtaining the appropriate angular precision including an axis deviation angle by simultaneously calculating the angle error and the axis deviation angle. A radar system mounted on a movable body is provided with a radar device that calculates relative speeds and azimuth angles of plural reflecting points; an azimuth angle error estimating device that estimates an error of the azimuth angle calculated by the radar device based on the relative speeds and the azimuth angles of the plural reflecting points; and a correcting device that corrects the azimuth angle calculated by the radar device by using the azimuth angle error estimated by the azimuth angle error estimating device.
