Abstract
Embodiments of this application disclose a signal processing method, a radar system, and a vehicle. The method is applied to a radar system including an array antenna. The method includes: sequentially transmitting signals according to a first transmission sequence through M transmit antennas, where the first transmission sequence is different from a sequence that is formed by arranging the M transmit antennas based on spatial locations; receiving, through N receive antennas, echo signals that are formed after a target reflects the transmitted signals, where M and N are positive integers, and M is greater than 2; and measuring a parameter of the target based on the echo signals. According to the embodiments of this application, correlation between space and a Doppler phase shift is reduced by changing a switching order of transmit antennas.
