Hi there, I am looking to retrieve the returning echo in terms of a time-domain signal. Inside, the library returns the strength of the returing echo in a normalized range of 0 - 255. However, I want to see the actual time frequency signal which is if i set 750 kHz then that, and the returning one which is the echo.
In another word, I want the original sending pulse, and receiving pulse for each angle.
I dont see function to extract this, however, in ping viewer these signals are displayed. I am adding the image to better explanation. Community help would be great.
