Abstract
An electronic device comprises a transmitting antenna that transmits a transmitted wave, a receiving antenna that receives a reflected wave obtained by reflection of the transmitted wave, and a controller. The controller generates a first sample based on a result obtained by subjecting a beat signal generated based on a transmitted signal based on the transmitted wave and a received signal based on the reflected wave to a first fast Fourier transform process. The controller generates a second sample based on a result obtained by subjecting the first sample to a second fast Fourier transform process, and estimates an arrival direction of the reflected wave based on the second sample. The controller sets the first sample from the beat signals in which the peak in the result obtained by performing the first fast Fourier transform process is equal to or higher than a first threshold value.
