A new method of determining scaleless range is proposed according to the characteristics of ballistic measurement data. The simulation and measured data processing results show that the method has high accuracy and good practicability. The FBM model was used to estimate the fractal dimension of a large number of measured data. The estimation results show that the fractal characteristics of the residual data of the ballistic measurement reflect the measurement environment and the target physical characteristics
