Abstract :
The analysis of data derived by full-waveform laser scanning systems is of great interest. In this study, we use a simulated surface response to estimate the slope of a plane surface by full-waveform analysis. For analysis the transmitted waveform of the emitted pulse is used to estimate the received waveform of the backscattered pulse for a known surface. We simulated a plane surface with different slopes. Typical spatial beam distributions are considered for modeling, namely Gaussian and uniform. The surface response is determined and the corresponding received waveform is calculated. The normalized cross-correlation function in between the estimated and the measured waveform is used to determine the slope of the surface. The similarity of the estimated and the measured received waveform is compared and discussed.
