1. A velocity measurement signal transmission method, comprising:
generating a plurality of chirp signals; and
transmitting the plurality of chirp signals in a time-division multiplexing (TDM) repetition cycle using M antennas,
wherein the TDM repetition cycle comprises a single-antenna transmit mode sub-cycle and L consecutive multi-antenna transmit mode sub-cycles,
wherein the single-antenna transmit mode sub-cycle comprises N frequency sweep cycles,
wherein transmitting the chirp signals further comprises transmitting N chirp signals of the chirp signals in the N frequency sweep cycles by one of the M antennas or simultaneously transmitting the N chirp signals by at least two of the M antennas,
wherein there is a delay between at least two of the M antennas,
wherein each multi-antenna transmit mode sub-cycle of the L consecutive multi-antenna transmit mode sub-cycles comprises M frequency sweep cycles,
wherein M chirp signals of the chirp signals in the M frequency sweep cycles are respectively transmitted in order by the M antennas,
wherein M and N are positive integers greater than 1, and
wherein L is a positive integer.
