I did a measurement in the acoustical lab to detect a range of a target by using continues acoustical chirps
i used speaker as transmitter and two microphones to record the transmitted and reflected sound signals at the same time to achieve the sync between them.
to do the analysis i have to multiply tow signals to get the shifted frequency.
receiver's microphone had been received the reflected signal and an effection from transmitter(speaker)
how can i remove this effection?
