Hi @abubakrazam,
That depends what you mean. Physically speaking the profile data is simply a measure of acoustic intensity that matches the frequency of a transmitted sonar pulse, which fundamentally is not a measurement of distance, so it’s not possible to get a distance reading from the profile. In practice, that acoustic intensity measurement tends to correlate reasonably well with acoustic reflections from objects hit by the sonar beam, and given a speed of sound in the transmission medium it’s possible to estimate the distance to the surface of the object that reflected the pulse. As a notable caveat, there are some materials and shapes that don’t reflect the pulse back towards the device, so not all objects can be equally well detected.
I’d recommend reading through these threads:
