Abstract
(EN) An information measurement method comprises: simultaneously transmitting a first measurement signal and a second measurement signal (101); after the first measurement signal has been reflected by a target, receiving the reflected first measurement signal as a first reflected signal, and after the second measurement signal has been reflected by the target, receiving the reflected second measurement signal as a second reflected signal (102); and performing computation to obtain state information of the target according to a difference between the first measurement signal and the first reflected signal, and a difference between the second measurement signal and the second reflected signal (103). Also provided is an information measurement device.
