中文摘要：

首先分析不同目标反射模型的漫反射激光测距方程的表达形式，然后通过对有合作目标的卫星激光测距和漫反射激光测距的特性对比分析，在理论上推导出适合1．2m望远镜激光测距系统的漫反射激光测距方程的一般形式。方程的最终表达形式与目标的形状、反射率和目标表面的漫反射特性函数有关。最后进行了地面靶板漫反射激光测距试验，并以试验为例来说明如何求解方程里特定的参数。

英文摘要：

The equations of Laser Ranging Based on Diffuse Reflection （LRBDR） for different models of target refection are analyzed. General equations are derived theoretically for LRBDR using a 1.2m telescope by comparing the characteristics of Satellite Laser Ranging for cooperative targets to those of LRBDR. These equations involve the target shape, reflectivity, and diffuse-refection distribution function of the target surface. Finally, a test of LRBDR with a ground-based target has been carried out, and it is taken as an example of how to measure the specific parameters in the equations.
