Abstract
A signal transmission method applied to a multiple-input multiple-output (MIMO) radar, the MIMO radar includes a transmitter, and the transmitter includes a plurality of transmit antennas. The signal transmission method includes sending, by the transmitter, a first burst in a first measurement frame, where the first measurement frame is used to measure a velocity of a target, and when the first burst is sent, each of the plurality of transmit antennas sends a chirp signal in a time division manner, and sending, by the transmitter, a second burst in the first measurement frame after the transmitter sends the first burst in the first measurement frame, where when the second burst is sent, a quantity of transmit antennas configured to send a chirp signal is one.
