I have ordered a USRP kit to do radio signal processing in software. Is there a way to use the same device to process sonar data? What would I do upconvert the sonar to 50 MHz?

  • $\begingroup$ What is the frequency and bandwidth of the sonar data? $\endgroup$ – Jim Clay Dec 19 '13 at 22:04
  • $\begingroup$ @Jim Clay Sonar data is 30 Hz to 20 KHz and there may be perhaps 100 or 1000 samples per second. $\endgroup$ – Tyler Durden Dec 19 '13 at 22:17
  • $\begingroup$ I don't understand- is the data digitized already? If it isn't, what do you mean by "100 or 1000 samples per second"? If it is, how do you cover 20 kHz with 1000 samples/s? And why do you want to convert it to analog so that you can put it into a USRP? You could just process the digitized data directly. $\endgroup$ – Jim Clay Dec 19 '13 at 22:21

    $\begingroup$ What do you need a USRP for if you want to do sonar in the range of 0-30 kHz?! Just use a soundcard instead of a USRP. The GnuRadio software is able to use soundcards as sources and sinks as well. $\endgroup$ – sellibitze Dec 20 '13 at 8:58
  • $\begingroup$ Thats a good point. $\endgroup$ – Tyler Durden Dec 20 '13 at 15:43
