For a correct use of metrics derived from processing of the full-waveform return signal from airborne laser scanner sensors any\udcorrelation which is not related to properties of the reflecting target must be known and, if possible, removed. In the following article\udwe report on an analysis of correlation between several metrics extracted from the full-waveform return signal and scan\udcharacteristics (mainly range) and type of land-cover (urban, grasslands, forests). The metrics taken in consideration are the\udamplitude, normalized amplitude, width (full width at half maximum), asymmetry indicators, left and right energy content, and the\udcross-section calculated from width and normalized amplitude considering the range effect. The results show that scan geometry in\udthis case does not have a significant impact scans over forest cover, except for range affecting amplitude and width distribution. Over\udcomplex targets such as vegetation canopy, other factors such as incidence angle have little meaning, therefore corrections of range\udeffect are the most meaningful. A strong correlation with the type of land-cover is also shown by the distribution of the values of the\udmetrics in the different areas taken in consideration
