RADAR DEVICE AND ANTENNA ANGLE ADJUSTING METHOD
First Claim
1. A radar device comprising:
- a housing;
a planar antenna tiltably provided with respect to the housing;
a detecting section that detects a tilt angle of the planar antenna with respect to the gravity direction;
a moving section that moves the planar antenna to adjust the tilt angle of the planar antenna; and
a storage section that stores a history of the tilt angle of the planar antenna and a tiltable range of the planar antenna with respect to the housing,wherein the moving section moves the planar antenna by a first angle to adjust the tilt angle of the planar antenna to a reference angle if the sum of the history of the tilt angle of the planar antenna and the first angle is within the tiltable range of the planar antenna, andwherein the moving section does not move the planar antenna by the first angle if the sum of the history of the tilt angle of the planar antenna and the first angle is beyond the tiltable range of the planar antenna.

Abstract
A radar device is provided. A planar antenna is tiltably provided with respect to a housing. A detecting section detects a tilt angle of the planar antenna with respect to the gravity direction. A moving section moves the planar antenna to adjust the tilt angle of the planar antenna. A storage section stores a history of the tilt angle of the planar antenna and a tiltable range of the planar antenna with respect to the housing. The moving section moves the planar antenna by a first angle to adjust the tilt angle of the planar antenna to a reference angle if the sum of the history of the tilt angle of the planar antenna and the first angle is within the tiltable range of the planar antenna. The moving section does not move the planar antenna by the first angle if the sum of the history of the tilt angle of the planar antenna and the first angle is beyond the tillable range of the planar antenna.

9. A radar device comprising:
-
a tilt angle detecting section that detects a tilt angle of an antenna with respect to a target angle; an adjusting section that adjusts an angle of the antenna from the tilt angle to the target angle; a calculating section that calculates an estimation value which is a criterion for determining whether or not an adjustment from the tilt angle to the target angle is performed as planned; a measurement value detecting section that detects a measurement value in accordance with variation in the angle of the antenna during the adjustment from the tilt angle to the target angle; and an adjustment failure detecting section that detects a failure of the adjustment on the basis of an error between the estimation value and the measurement value. - View Dependent Claims (10, 11, 12, 13)
