PROBLEM TO BE SOLVED: To provide an object detection sensor which can measure an objective position with a sufficient accuracy for the vicinity just under the sensor including a predetermined monitoring region. SOLUTION: The position and the height in the objective supervision face are measured for just under the installed sensor by partitioning the monitoring region into a plurality of compartments 11, 12 and 13 according to a distance from the sensor 2, switching and using a plurality of antennas 3, 4 and 5 which make each compartment detection extent, and comparing the outgoing information and the electric wave irradiation course of a radio wave radar in a signal processing circuit 8.
