根据激光测距机对漫反射大目标的测距方程,从理论上分析了激光测距机的测距性能与大气透过率及背景噪声之间的关系;并使用LOWTRAN7软件,对它们之间的依赖关系进行了数值计算与深入探讨,为机载激光测距机的测程指标的设计及测试提供了依据。

The dependence of ranging performance for an airborne laser range finder on atmospheric transmittance and background noise is theoretically analyzed in accordance with the range equation for the diffuse reflecting target. Based on LOWTRAN7 code, the dependent relationship between them is numerically calculated and discussed. The numerical result can be used as the basis for design and test of the range index for an airborne laser range finder.
