Beschreibung
Zusammenfassung:	A signal processing method and apparatus are provided, to ensure orthogonality between detection signals transmitted by different transmit antennas, so that angular resolution of target detection is increased. The method includes: determining and sending a first sequence set, where the first sequence set includes at least one first sequence, and the at least one first sequence is an orthogonal sequence obtained after fast-time dimension coding and slow-time dimension coding; and then, receiving a reflected signal of the first sequence set, and determining one or more of a distance, a velocity, and an azimuth of a detection target based on the reflected signal.
