1. An electronic device comprising: a plurality of sensors installed in predetermined orientations at different positions,
each of the plurality of sensors comprising:
a transmission antenna that transmits a transmission wave;
a reception antenna that receives a reflected wave that is the transmission wave having been reflected; and
a first processor configured to detect an object that reflects the transmission wave, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave,
the electronic device further comprising: a second processor configured to determine a shift in orientation of at least any of the plurality of sensors, based on detection results of the object obtained by the plurality of sensors, wherein:
the plurality of sensors comprise a first sensor, a second sensor, and a third sensor,
the first sensor and the second sensor are installed in predetermined orientations such that an object detection range of the first sensor and an object detection range of the second sensor partially overlap,
the second processor is configured to determine a shift in orientation of either the first sensor or the second sensor, based on detection results of an identical object obtained by the first sensor and the second sensor,
the third sensor is installed in a predetermined orientation such that the object detection range of the second sensor partially overlaps with the object detection range of the first sensor and with an object detection range of the third sensor, and
the second processor is configured to determine whether the orientations of both the first sensor and the second sensor are shifted, based on detection results of an identical second object obtained by the third sensor and another sensor in a case where locations detected for an identical first object by the first sensor and the second sensor are within a predetermined distance, wherein the predetermined distance is determined on a basis of object detection accuracy of the electronic device.
