Claim 16:
17. A radar apparatus for use in a vehicle, the apparatus comprising:
a radar housing;
a radar sensor provided within the radar housing;
a movable support that comprises:
a first part fixed relative to a body of the vehicle,
a second part fixed relative to the radar housing, and
an actuator for moving the second part between first and second positions relative to the first part while the vehicle is stationary around an axis that is fixed relative to the vehicle body,

a first 3 axis accelerometer fixed in position relative to the radar sensor and having a first signal output;
a second 3 axis accelerometer fixed in position relative to the vehicle and having a second signal output; and
a signal processing apparatus that receives the first and second signal outputs and compares the first and second signal outputs when the second part is in the first position to determine a misalignment of the radar sensor in pitch and roll and compares the first and second signal outputs when the second part is in the second position for determining a misalignment of the radar sensor in yaw.
