Abstract: A radar signal transmitting method, a radar signal receiving method, and an apparatus are applied to a radar apparatus. The radar signal transmitting method includes: sending a first signal and a second signal in S slots, where a phase of the first signal remains unchanged in the S slots, and the first signal may be equivalent to a SIMO signal; and sending the second signal in at least one of a time division manner or a code division manner, where phase modulation is performed, by using a step of 2πky/P, on a signal that is in the second signal and that is sent through each of m transmit antennas, and the second signal is equivalent to a MIMO signal. When P=2, the MIMO signal is sent in a time division manner. When P>2, the MIMO signal is sent in a time division manner and a code division manner.
