The Impact of Laser Echo Waveform of Slope Terrain on Ranging Precision
The impact of the waveforms of return signal from slope terrains on ranging precision was studied to improve the ranging performance.The expression of laser echo was introduced and then based on it the echo stretch of slope terrain was discussed.The ranging performances of threshold method,CFD and waveform centroidal method were analyzed,the results indicate that waveform centroidal method is the most available.
