摘要： 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.

摘要： The present invention relates to a method for terminal positioning. The method comprises: generating cell-specific reference signals CRSs, and transmitting the CRSs on one or more ports used for transmitting the CRSs; generating a positioning reference signal PRS, and transmitting the PRS on one of the one or more ports used for transmitting the CRSs. The method for terminal positioning provided by the embodiment of the present invention can reduce an impact caused by the limited number of symbols for transmitting the PRS, and increase the number of reference signal symbols available for positioning within a subframe, thereby reducing an impact of a secondary peak and enhancing the energy of a primary peak.
