Abstract: An electronic device includes: a radar sensor configured to radiate a radar signal and receive a reflected signal of the radiated radar signal by: transmitting at least some chirp signals among a plurality of chirp signals belonging to the same frame through a single antenna among a plurality of antennas of the radar sensor; and transmitting other chirp signals among the plurality of chirp signals belonging to the same frame through at least two antennas among the plurality of antennas; and one or more processors configured to detect a target and determine a direction of arrival (DOA) of the target from radar data determined based on the at least some chirp signals, the other chirp signals, and the reflected signal.
