<p>PURPOSE:To obtain the positional information of an object with high accuracy, by correcting a measured height data on the basis of the tilt angle of a reference surface representing a beam direction. CONSTITUTION:When external force is acted on the antenna 4 provided to a base stand 5 to incline the same by theta deg., the inclinations of a beam direction and a reference surface also similarily changed by theta deg.. A tilt angle automatic detector 2 detects this inclination theta deg. and transmits the same to a measured height data correcting part 3 as a voltage change amount. The correcting part 3 correct measured height data sent from the antenna 4 on the basis of the inclination value to output final measured height data.</p> |
