Title:
SIGNAL PROCESSING METHOD AND DEVICE, RADAR DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/258292
Kind Code:
A1
Abstract:
A signal processing method and device, a radar device and a storage medium, belonging to the technical field of radars. The signal processing method comprises: acquiring a plurality of signals received by a first receiving antenna, wherein the plurality of signals are respectively transmitted by a plurality of transmitting antenna groups in a time division multiplexing manner, the plurality of transmitting antennas in each transmitting antenna group transmit signals in a Doppler frequency division multiplexing manner, and the first receiving antenna is any one of a plurality of receiving antennas for receiving signals transmitted by the transmitting antennas (402); respectively acquiring first range-Doppler transform data of signals transmitted by each transmitting antenna group in the plurality of signals (403); and combining a plurality of first range-Doppler transform data to obtain second range-Doppler transform data of the plurality of signals received by the first receiving antenna (404). The method reduces the amount of computation for obtaining the second range-Doppler transform data.
