SIGNAL TRANSMISSION METHOD AND DEVICE, SIGNAL PROCESSING METHOD AND DEVICE, AND RADAR SYSTEM

A signal transmission method and apparatus (1300), a signal processing method and apparatus (1400), and a radar system (1500) are provided, so that a MIMO radar can accurately resume a velocity measurement of a target to a velocity measurement range of a SIMO radar. The signal transmission method is applied to a multiple input multiple output (MIMO) radar. A transmitter (1301, 1501) in the MIMO radar sends a measurement frame used to measure a velocity of a target (S301). The measurement frame includes a first burst. In the first burst, each low-density transmit antenna sends one chirp signal in each timeslot, and at least one high-density transmit antenna sends more chirp signals in additional timeslots.
