Using sound to extract information

  1. Jan 26, 2010 #1

    I need to use sound to echolocate something. I need to find a way to describe the doppler frequency as a function of time, using a recording of the sound it makes while moving.

    Any ideas?

    The doppler shift can be analyzed for the velocity, echo location for distances.
