Processing/LiDARIntensity
v1 v2 4 4 5 5 6 As well as the time / range of the echo return, the system also measures the intensity (peak power) of the echo. Currently this value is not calibrated nor comparable along the flight line. This is due to the automatic gain control of the system (AGC), where the echo power is amplified by different amounts dependant on the return strength. This can result in a ``striping'' effect in the intensity images.6 As well as the time / range of the echo return, the system also measures the intensity (peak power) of the echo.
