1. A method comprising:
sending a first measurement frame at a duty cycle of P %, wherein P<100, wherein the duty cycle is equal to a ratio of a first duration of the first measurement frame to a second duration, and wherein the second duration is a time difference between two adjacent measurement frames received from a transmitter of a multiple-input multiple-output (MIMO) radar;
sending a first burst in the first measurement frame for measuring a velocity of a target, wherein each of a plurality of transmit antennas of the transmitter sends a first chirp signal in the first burst in a time-division multiplexing (TDM) manner; and
sending, in response to sending the first burst, a second burst in the first measurement frame, wherein a first quantity of the transmit antennas configured to send a second chirp signal in the second burst is one when the second burst is sent.
