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.
Claims19
An electronic device comprising:
- a radar sensor configured to radiate a radar signal and receive a reflected signal of the radiated radar signal by:
- transmitting one or more 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 one or more chirp signals, the other chirp signals, and the reflected signal,
- wherein the radar sensor is configured to:
- for the transmitting of the one or more chirp signals, transmit the one or more chirp signals generated based on a first carrier frequency, through the single antenna;
- and
- for the transmitting of the other chirp signals, transmit the other chirp signals generated based on a second carrier frequency different from the first carrier frequency, through the at least two antennas.
An electronic device comprising:
- a radar sensor configured to radiate a radar signal and receive a reflected signal of the radiated radar signal by:
- transmitting one or more 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 one or more chirp signals, the other chirp signals, and the reflected signal,
- wherein each of a plurality of chirp sequences included in the same frame includes the same number of time slots as a number of transmit antennas included in the radar sensor.
A processor-implemented method with radar signal processing, the method comprising:
- transmitting one or more chirp signals among a plurality of chirp signals belonging to the same frame through a single antenna among a plurality of antennas;
- 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
- detecting a target and determining a direction of arrival (DOA) of the target from radar data determined based on the one or more chirp signals, the other chirp signals, and a reflected signal,
- wherein the transmitting of the one or more chirp signals includes transmitting the one or more chirp signals generated based on a first carrier frequency, through the single antenna, and
- wherein the transmitting of the other chirp signals includes transmitting the other chirp signals generated based on a second carrier frequency different from the first carrier frequency, through the at least two antennas.
