Impaction of Gauss fitting-error on ranging precision

WANG Huan1,LI Song1,ZHOU Hui2 (1.School of Electronic Information,Wuhan University,Wuhan 430079,China; 2.School of Geodesy and Geomatics,Wuhan University,Wuhan 430079,China)  
The procedure to setup a return signal model of laser altimeter was given.The waveforms of return signal from slope terrains were simulated.The impaction of Gauss fitting-error on ranging precision was used to determine whether return signal was Gaussian or not.The difference between optimum fitting-waveforms and practical waveforms of MOLA return signal,with different target slope angle and threshold value,were obtained by using LM nonlinear algorithm.The impaction of fitting-error on ranging precision of MOLA was analyzed.The result reveals that the impaction is too small to be considered.It means that it is feasible to regard the return signal of MOLA as Gaussian shape.
