Abstract
An electronic apparatus is disclosed. The electronic apparatus includes: a communication interface comprising communication circuitry and a processor configured to: control the communication interface to transmit a signal of a first carrier frequency, and based on a signal generated as the signal of the first carrier frequency reflected by a space where the electronic apparatus is disposed not being received through the communication interface within a first threshold time after the signal of the first carrier frequency is transmitted, determine the first carrier frequency as a search carrier frequency; based on the reflected signal being received through the communication interface within the first threshold time after the signal of the first carrier frequency is transmitted, control the communication interface to transmit a signal of a second carrier frequency different from the first carrier frequency; control the communication interface to transmit a signal of the determined search carrier frequency; and identify whether an object is present based on whether a signal is received through the communication interface within a second threshold time after the signal of the search carrier frequency is transmitted.
