Beschreibung
Zusammenfassung:	The invention provides a signal sending method and device, and the method comprises the steps: determining T code word sequences corresponding to T transmitting antennas in a one-to-one manner according to the number T of the transmitting antennas of a radar and the number NC of signals transmitted by each transmitting antenna in a frame, each code word sequence in the T code word sequences comprising NC code words, each codeword sequence is used for processing NC signals of one transmitting antenna, T is greater than 1, NC is greater than or equal to 1, and T and NC are integers; the Doppler spectrum corresponding to the T code word sequences comprises a first region corresponding to a main lobe, and a second region and a third region corresponding to a side lobe, and the maximum peak value of the side lobe in the second region is smaller than the maximum peak value of the side lobe in the third region. Therefore, the Doppler dimension dynamic state in the second area is large, the probability of missed dete
