Sonar Data Question - Sb12345 - 10-03-2020 I’m having trouble understanding what the data for sonar means. For example, in the Time.csv file I’m not sure what the correlation is correlating. Is there any place I can find out? Inalready checked the wikipedia page. RE: Sonar Data Question - Jens Noriʇzsɔɥ - 10-03-2020 The time data is more or less the “raw” cross correlation data, a bit smoothened though and the first 2ms cut out. The output multi chirp (speaker) is cross correlated against the audio input (microphone). The time data shows how well they match for the displayed range of time differences. |
