We have developed an application to log the raw data from the Ping sonar and have noticed a weird artefact when viewing the data.
We have noticed that in certain points the raw data appears to be smoothed as can be seen in the attached image. The data from the left hand side of the image is quite different to what we are normally seeing on the right hand side.
We are not doing an processing at any point so this must be the raw output from the Ping itself.
Does anyone have any information?
