In this thesis, the above mentioned critical measurement situations are investigated by the analysis of the temporal waveform to improve the capabilities of terrestrial and airborne laser scanning systems. In total seven methods are presented to gain additional possibilities for object representations. For object description the features are derived by the waveform, namely range, range variation, and reflectivity. These features are investigated and the achieved results are discussed, evaluated and compared. With the Wiener Filtering a new procedure was invented for an improved discrimination of several areas with slightly different elevations. An example is given, that demonstrates a discrimination of two areas, with a range difference of 0.15m for a typical pulse length of 5ns, can be distinguished.
