1. An electronic device 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 processor that detects a target by using a constant false alarm rate, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave, wherein
the processor sets a test region and at least one or more reference regions with respect to the test region in a distribution of signal intensities based on the reception signal in a distance direction, and sets a threshold for use in detection of the target, based on an order statistic among signal intensities in the reference regions,
wherein the processor is configured to switch between a plurality of patterns including: at least one or more patterns in which the reference regions are set on a near side with respect to the test region in the distance direction in the distribution of the signal intensities based on the reception signal in the distance direction, and at least one or more additional patterns.
