Acoustic radar project for students

  1. Jan 21, 2012 #1
    I came across an article in American Journal of Physics recently that describes how to build an acoustic radar by transmitting a carrier modulated with pseudo-noise code through a speaker and simultaneously receiving the reflection with a directional microphone. One then does some signal processing to get the resulting pulse profile as a function of distance. It was originally conceived as a radar or lidar simulator.

    Hi cowboy3, welcome to PF

    That seems like a pretty fun project!

    Btw, another word for "acoustic radar" is "sonar".

    I think the term acoustic radar and sodar are commonly used for sonar in air though sonar is correct also.
