| Abstract: | The impacts on laser radar cross section measure are analyzed because of the non-uniformity of the luminous intensity and the incident laser pulse being stretched by the measured target. Considering the two factors, the new measure equation and calculation method of laser radar cross section are derived and applied to the actual targets. The results show that the impacts on measure are avoided by application of this new method because of the non-uniformity as well as the stretched pulse, then the measure accuracy is improved. |
