根据激光测距方程,分别建立了激光测距机漫反射目标及合作目标测距能力的理论模型。通过数值计算,研究了不同大气能见度条件下及不同激光发射束散角条件下配置合作目标对激光测距能力的影响。结果表明,配置合作目标可有效提高测距能力,并且在有合作目标条件下可有效降低激光发射功率,进一步为提高人眼安全提供保障。

The laser range finders ranging performance theoretical models of diffuse target and cooperative target are established based on the laser ranging equation. And the effects of cooperative target on ranging performance are discussed at different atmospheric visibility and different beam divergence angle. The results show that cooperative target can increase the ranging performance, decrease the laser emission power efficiently, and ensure personnel safety accordingly.
