A Method of Measuring Velocities Based on Curve Fitting by Pulsed Laser Radar

A method based on least-squares curve fitting is introduce to acquired the information of velocity of the pulsed laser radar's object. The exponential function and the orthogonal function are taken as fundus to fit curve respectively, and their fitting performance have been compared by the analysis of the measuring deviation of them, and then choose the exponential function is chose as fundus to fit curve to acquire the information of velocity of object.
