Title:
MULTI-TARGET DETECTION APPARATUS AND METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/001018
Kind Code:
A1
Abstract:
A multi-target detection apparatus and method, and an electronic device. The multi-target detection apparatus (1) comprises a processor (10), a transmitter (11) and a receiver (12). The processor (10) is used for: controlling the transmitter (11) to transmit a first pulse (31), and controlling the receiver (12) to receive a plurality of first echoes (21) generated from the first pulse (31) respectively reflected by a plurality of targets (2); obtaining, according to the time difference from transmitting the first pulse (31) to receiving the plurality of first echoes (21), signal flight times respectively corresponding to the plurality of targets (2); determining the time interval between two adjacent pulses among a plurality of second pulses (41) according to the signal flight times corresponding to the plurality of targets (2); controlling, according to the time interval, the transmitter (11) to transmit the plurality of second pulses (41), and controlling the receiver (12) to receive a plurality of second echoes (22) generated from each second pulse (41) respectively reflected by the plurality of targets (2); and obtaining vital signs of the plurality of targets (2) according to the transmission times of the plurality of second pulses (41), the receiving times of the plurality of second echoes (22) corresponding to each second pulse (41), and the signal flight times corresponding to the plurality of targets (2).
