jm211 Posted January 23, 2012 Share Posted January 23, 2012 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. http://ajp.aapt.org/...79/i12/p1240_s1 Link to comment Share on other sites More sharing options...
